-- **JSON Processing**: com.alibaba.fastjson2:fastjson2
-- **Testing**: JUnit 5 (org.junit.jupiter:junit-jupiter)
-
-## Installation
-
-Add the following dependency to your Maven `pom.xml`:
-
-```xml
-<dependency>
-    <groupId>com.alibaba</groupId>
-    <artifactId>qwencode-sdk</artifactId>
-    <version>{$version}</version>
-</dependency>
-```
-
-Or if using Gradle, add to your `build.gradle`:

-# Compile the project
-mvn compile
-
-# Run tests
-mvn test
-
-# Package the JAR
-mvn package
-
-# Install to local repository
-mvn install
-```
-
-## Quick Start
-
-The simplest way to use the SDK is through the `QwenCodeCli.simpleQuery()` method:
-
-```java
-public static void runSimpleExample() {
-    List<String> result = QwenCodeCli.simpleQuery("hello world");
-    result.forEach(logger::info);
-}
-```
-
-For more advanced usage with custom transport options:
-
-```java
-public static void runTransportOptionsExample() {
-    TransportOptions options = new TransportOptions()
-            .setModel("qwen3-coder-flash")
-            .setPermissionMode(PermissionMode.AUTO_EDIT)
-            .setCwd("./")
-            .setEnv(new HashMap<String, String>() {{put("CUSTOM_VAR", "value");}})
-            .setIncludePartialMessages(true)
-            .setTurnTimeout(new Timeout(120L, TimeUnit.SECONDS))
-            .setMessageTimeout(new Timeout(90L, TimeUnit.SECONDS))
-            .setAllowedTools(Arrays.asList("read_file", "write_file", "list_directory"));
-
-    List<String> result = QwenCodeCli.simpleQuery("who are you, what are your capabilities?", options);
-    result.forEach(logger::info);
-}
-```
-
-For streaming content handling with custom content consumers:
-
-```java
-public static void runStreamingExample() {
-    QwenCodeCli.simpleQuery("who are you, what are your capabilities?",
-            new TransportOptions().setMessageTimeout(new Timeout(10L, TimeUnit.SECONDS)), new AssistantContentSimpleConsumers() {
-
-                @Override
-                public void onText(Session session, TextAssistantContent textAssistantContent) {
-                    logger.info("Text content received: {}", textAssistantContent.getText());
-                }
-
-                @Override
-                public void onThinking(Session session, ThingkingAssistantContent thingkingAssistantContent) {
-                    logger.info("Thinking content received: {}", thingkingAssistantContent.getThinking());
-                }
-
-                @Override
-                public void onToolUse(Session session, ToolUseAssistantContent toolUseContent) {
-                    logger.info("Tool use content received: {} with arguments: {}",
-                            toolUseContent, toolUseContent.getInput());
-                }
-
-                @Override
-                public void onToolResult(Session session, ToolResultAssistantContent toolResultContent) {
-                    logger.info("Tool result content received: {}", toolResultContent.getContent());
-                }
-
-                @Override
-                public void onOtherContent(Session session, AssistantContent<?> other) {
-                    logger.info("Other content received: {}", other);
-                }
-
-                @Override
-                public void onUsage(Session session, AssistantUsage assistantUsage) {
-                    logger.info("Usage information received: Input tokens: {}, Output tokens: {}",
-                            assistantUsage.getUsage().getInputTokens(), assistantUsage.getUsage().getOutputTokens());
-                }
-            }.setDefaultPermissionOperation(Operation.allow));
-    logger.info("Streaming example completed.");

-
-## Architecture
-
-The SDK follows a layered architecture:
-
-- **API Layer**: Provides the main entry points through `QwenCodeCli` class with simple static methods for basic usage
-- **Session Layer**: Manages communication sessions with the Qwen Code CLI through the `Session` class
-- **Transport Layer**: Handles the communication mechanism between the SDK and CLI process (currently using process transport via `ProcessTransport`)
-- **Protocol Layer**: Defines data structures for communication based on the CLI protocol
-- **Utils**: Common utilities for concurrent execution, timeout handling, and error management
-
-## Key Features
-
-### Permission Modes
-
-The SDK supports different permission modes for controlling tool execution:
-
-- **`default`**: Write tools are denied unless approved via `canUseTool` callback or in `allowedTools`. Read-only tools execute without confirmation.
-- **`plan`**: Blocks all write tools, instructing AI to present a plan first.
-- **`auto-edit`**: Auto-approve edit tools (edit, write_file) while other tools require confirmation.
-- **`yolo`**: All tools execute automatically without confirmation.
-
-### Session Event Consumers and Assistant Content Consumers
-
-The SDK provides two key interfaces for handling events and content from the CLI:
-
-#### SessionEventConsumers Interface
-
-The `SessionEventConsumers` interface provides callbacks for different types of messages during a session:
-
-- `onSystemMessage`: Handles system messages from the CLI (receives Session and SDKSystemMessage)
-- `onResultMessage`: Handles result messages from the CLI (receives Session and SDKResultMessage)
-- `onAssistantMessage`: Handles assistant messages (AI responses) (receives Session and SDKAssistantMessage)
-- `onPartialAssistantMessage`: Handles partial assistant messages during streaming (receives Session and SDKPartialAssistantMessage)
-- `onUserMessage`: Handles user messages (receives Session and SDKUserMessage)
-- `onOtherMessage`: Handles other types of messages (receives Session and String message)
-- `onControlResponse`: Handles control responses (receives Session and CLIControlResponse)
-- `onControlRequest`: Handles control requests (receives Session and CLIControlRequest, returns CLIControlResponse)
-- `onPermissionRequest`: Handles permission requests (receives Session and CLIControlRequest<CLIControlPermissionRequest>, returns Behavior)
-
-#### AssistantContentConsumers Interface
-
-The `AssistantContentConsumers` interface handles different types of content within assistant messages:
-
-- `onText`: Handles text content (receives Session and TextAssistantContent)
-- `onThinking`: Handles thinking content (receives Session and ThingkingAssistantContent)
-- `onToolUse`: Handles tool use content (receives Session and ToolUseAssistantContent)
-- `onToolResult`: Handles tool result content (receives Session and ToolResultAssistantContent)
-- `onOtherContent`: Handles other content types (receives Session and AssistantContent)
-- `onUsage`: Handles usage information (receives Session and AssistantUsage)
-- `onPermissionRequest`: Handles permission requests (receives Session and CLIControlPermissionRequest, returns Behavior)
-- `onOtherControlRequest`: Handles other control requests (receives Session and ControlRequestPayload, returns ControlResponsePayload)
-
-#### Relationship Between the Interfaces
-
-**Important Note on Event Hierarchy:**
-
-- `SessionEventConsumers` is the **high-level** event processor that handles different message types (system, assistant, user, etc.)
-- `AssistantContentConsumers` is the **low-level** content processor that handles different types of content within assistant messages (text, tools, thinking, etc.)
-
-**Processor Relationship:**
-
-- `SessionEventConsumers` → `AssistantContentConsumers` (SessionEventConsumers uses AssistantContentConsumers to process content within assistant messages)
-
-**Event Derivation Relationships:**
-
-- `onAssistantMessage` → `onText`, `onThinking`, `onToolUse`, `onToolResult`, `onOtherContent`, `onUsage`
-- `onPartialAssistantMessage` → `onText`, `onThinking`, `onToolUse`, `onToolResult`, `onOtherContent`
-- `onControlRequest` → `onPermissionRequest`, `onOtherControlRequest`
-
-**Event Timeout Relationships:**
-
-Each event handler method has a corresponding timeout method that allows customizing the timeout behavior for that specific event:
-
-- `onSystemMessage` ↔ `onSystemMessageTimeout`
-- `onResultMessage` ↔ `onResultMessageTimeout`
-- `onAssistantMessage` ↔ `onAssistantMessageTimeout`
-- `onPartialAssistantMessage` ↔ `onPartialAssistantMessageTimeout`
-- `onUserMessage` ↔ `onUserMessageTimeout`
-- `onOtherMessage` ↔ `onOtherMessageTimeout`
-- `onControlResponse` ↔ `onControlResponseTimeout`
-- `onControlRequest` ↔ `onControlRequestTimeout`
-
-For AssistantContentConsumers timeout methods:
-
-- `onText` ↔ `onTextTimeout`
-- `onThinking` ↔ `onThinkingTimeout`
-- `onToolUse` ↔ `onToolUseTimeout`
-- `onToolResult` ↔ `onToolResultTimeout`
-- `onOtherContent` ↔ `onOtherContentTimeout`
-- `onPermissionRequest` ↔ `onPermissionRequestTimeout`
-- `onOtherControlRequest` ↔ `onOtherControlRequestTimeout`
-
-**Default Timeout Values:**
-
-- `SessionEventSimpleConsumers` default timeout: 180 seconds (Timeout.TIMEOUT_180_SECONDS)
-- `AssistantContentSimpleConsumers` default timeout: 60 seconds (Timeout.TIMEOUT_60_SECONDS)
-
-**Timeout Hierarchy Requirements:**
-
-For proper operation, the following timeout relationships should be maintained:
-
-- `onAssistantMessageTimeout` return value should be greater than `onTextTimeout`, `onThinkingTimeout`, `onToolUseTimeout`, `onToolResultTimeout`, and `onOtherContentTimeout` return values
-- `onControlRequestTimeout` return value should be greater than `onPermissionRequestTimeout` and `onOtherControlRequestTimeout` return values
-
-### Transport Options
-
-The `TransportOptions` class allows configuration of how the SDK communicates with the Qwen Code CLI:
-
-- `pathToQwenExecutable`: Path to the Qwen Code CLI executable
-- `cwd`: Working directory for the CLI process
-- `model`: AI model to use for the session
-- `permissionMode`: Permission mode that controls tool execution
-- `env`: Environment variables to pass to the CLI process
-- `maxSessionTurns`: Limits the number of conversation turns in a session
-- `coreTools`: List of core tools that should be available to the AI
-- `excludeTools`: List of tools to exclude from being available to the AI
-- `allowedTools`: List of tools that are pre-approved for use without additional confirmation
-- `authType`: Authentication type to use for the session
-- `includePartialMessages`: Enables receiving partial messages during streaming responses
-- `skillsEnable`: Enables or disables skills functionality for the session
-- `turnTimeout`: Timeout for a complete turn of conversation
-- `messageTimeout`: Timeout for individual messages within a turn
-- `resumeSessionId`: ID of a previous session to resume
-- `otherOptions`: Additional command-line options to pass to the CLI
-
-### Session Control Features
-
-- **Session creation**: Use `QwenCodeCli.newSession()` to create a new session with custom options
-- **Session management**: The `Session` class provides methods to send prompts, handle responses, and manage session state
-- **Session cleanup**: Always close sessions using `session.close()` to properly terminate the CLI process
-- **Session resumption**: Use `setResumeSessionId()` in `TransportOptions` to resume a previous session
-- **Session interruption**: Use `session.interrupt()` to interrupt a currently running prompt
-- **Dynamic model switching**: Use `session.setModel()` to change the model during a session
-- **Dynamic permission mode switching**: Use `session.setPermissionMode()` to change the permission mode during a session
-
-### Thread Pool Configuration
-
-The SDK uses a thread pool for managing concurrent operations with the following default configuration:
-
-- **Core Pool Size**: 30 threads
-- **Maximum Pool Size**: 100 threads
-- **Keep-Alive Time**: 60 seconds
-- **Queue Capacity**: 300 tasks (using LinkedBlockingQueue)
-- **Thread Naming**: "qwen_code_cli-pool-{number}"
-- **Daemon Threads**: false
-- **Rejected Execution Handler**: CallerRunsPolicy
-
-## Error Handling
-
-The SDK provides specific exception types for different error scenarios:
-
-- `SessionControlException`: Thrown when there's an issue with session control (creation, initialization, etc.)
-- `SessionSendPromptException`: Thrown when there's an issue sending a prompt or receiving a response
-- `SessionClosedException`: Thrown when attempting to use a closed session
-
-## FAQ / Troubleshooting
-
-### Q: Do I need to install the Qwen CLI separately?
-
-A: yes, requires Qwen CLI 0.5.5 or higher.
-
-### Q: What Java versions are supported?
-
-A: The SDK requires Java 1.8 or higher.
-
-### Q: How do I handle long-running requests?
-
-A: The SDK includes timeout utilities. You can configure timeouts using the `Timeout` class in `TransportOptions`.
-
-### Q: Why are some tools not executing?
-
-A: This is likely due to permission modes. Check your permission mode settings and consider using `allowedTools` to pre-approve certain tools.
-
-### Q: How do I resume a previous session?
-
-A: Use the `setResumeSessionId()` method in `TransportOptions` to resume a previous session.
-
-### Q: Can I customize the environment for the CLI process?
-
-A: Yes, use the `setEnv()` method in `TransportOptions` to pass environment variables to the CLI process.

-## Customizing the sandbox environment (Docker/Podman)
-
-### Currently, the project does not support the use of the BUILD_SANDBOX function after installation through the npm package
-
-1. To build a custom sandbox, you need to access the build scripts (scripts/build_sandbox.js) in the source code repository.
-2. These build scripts are not included in the packages released by npm.
-3. The code contains hard-coded path checks that explicitly reject build requests from non-source code environments.
-
-If you need extra tools inside the container (e.g., `git`, `python`, `rg`), create a custom Dockerfile, The specific operation is as follows
-
-#### 1、Clone qwen code project first, https://github.com/QwenLM/qwen-code.git
-
-#### 2、Make sure you perform the following operation in the source code repository directory
-
-```bash
-# 1. First, install the dependencies of the project
-npm install
-
-# 2. Build the Qwen Code project
-npm run build
-
-# 3. Verify that the dist directory has been generated
-ls -la packages/cli/dist/
-
-# 4. Create a global link in the CLI package directory
-cd packages/cli
-npm link
-
-# 5. Verification link (it should now point to the source code)
-which qwen
-# Expected output: /xxx/xxx/.nvm/versions/node/v24.11.1/bin/qwen
-# Or similar paths, but it should be a symbolic link
-
-# 6. For details of the symbolic link, you can see the specific source code path
-ls -la $(dirname $(which qwen))/../lib/node_modules/@qwen-code/qwen-code
-# It should show that this is a symbolic link pointing to your source code directory
-
-# 7.Test the version of qwen
-qwen -v
-# npm link will overwrite the global qwen. To avoid being unable to distinguish the same version number, you can uninstall the global CLI first
-```
-
-#### 3、Create your sandbox Dockerfile under the root directory of your own project
-
-- Path: `.qwen/sandbox.Dockerfile`
-
-- Official mirror image address:https://github.com/QwenLM/qwen-code/pkgs/container/qwen-code
-
-```bash
-# Based on the official Qwen sandbox image (It is recommended to explicitly specify the version)
-FROM ghcr.io/qwenlm/qwen-code:sha-570ec43
-# Add your extra tools here
-RUN apt-get update && apt-get install -y \
-    git \
-    python3 \
-    ripgrep
-```
-
-#### 4、Create the first sandbox image under the root directory of your project
-
-```bash
-GEMINI_SANDBOX=docker BUILD_SANDBOX=1 qwen -s
-# Observe whether the sandbox version of the tool you launched is consistent with the version of your custom image. If they are consistent, the startup will be successful
-```
-
-This builds a project-specific image based on the default sandbox image.
-
-#### Remove npm link
-
-- If you want to restore the official CLI of qwen, please remove the npm link
-
-```bash
-# Method 1: Unlink globally
-npm unlink -g @qwen-code/qwen-code
-
-# Method 2: Remove it in the packages/cli directory
-cd packages/cli
-npm unlink
-
-# Verification has been lifted
-which qwen
-# It should display "qwen not found"
-
-# Reinstall the global version if necessary
-npm install -g @qwen-code/qwen-code
-
-# Verification Recovery
-which qwen
-qwen --version
-```

-The `customHeaders` field allows you to add custom HTTP headers to all API requests. This is useful for request tracing, monitoring, API gateway routing, or when different models require different headers. If `customHeaders` is defined in `modelProviders[].generationConfig.customHeaders`, it will be used directly; otherwise, headers from `model.generationConfig.customHeaders` will be used. No merging occurs between the two levels.

-#### modelProviders
-
-Use `modelProviders` to declare curated model lists per auth type that the `/model` picker can switch between. Keys must be valid auth types (`openai`, `anthropic`, `gemini`, `vertex-ai`, etc.). Each entry requires an `id` and **must include `envKey`**, with optional `name`, `description`, `baseUrl`, and `generationConfig`. Credentials are never persisted in settings; the runtime reads them from `process.env[envKey]`. Qwen OAuth models remain hard-coded and cannot be overridden.

-> Only the `/model` command exposes non-default auth types. Anthropic, Gemini, Vertex AI, etc., must be defined via `modelProviders`. The `/auth` command intentionally lists only the built-in Qwen OAuth and OpenAI flows.

-##### Resolution layers and atomicity

-
-\*When present, CLI auth flags override settings. Otherwise, `security.auth.selectedType` or the implicit default determine the auth type. Qwen OAuth and OpenAI are the only auth types surfaced without extra configuration.
-
-Model-provider sourced values are applied atomically: once a provider model is active, every field it defines is protected from lower layers until you manually clear credentials via `/auth`. The final `generationConfig` is the projection across all layers—lower layers only fill gaps left by higher ones, and the provider layer remains impenetrable.
-
-The merge strategy for `modelProviders` is REPLACE: the entire `modelProviders` from project settings will override the corresponding section in user settings, rather than merging the two.
-
-##### Generation config layering
-
-Per-field precedence for `generationConfig`:
-
-1. Programmatic overrides (e.g. runtime `/model`, `/auth` changes)
-2. `modelProviders[authType][].generationConfig`
-3. `settings.model.generationConfig`
-4. Content-generator defaults (`getDefaultGenerationConfig` for OpenAI, `getParameterValue` for Gemini, etc.)
-
-`samplingParams` and `customHeaders` are both treated atomically; provider values replace the entire object. If `modelProviders[].generationConfig` defines these fields, they are used directly; otherwise, values from `model.generationConfig` are used. No merging occurs between provider and global configuration levels. Defaults from the content generator apply last so each provider retains its tuned baseline.
-
-##### Selection persistence and recommendations
-
-> [!important]
-> Define `modelProviders` in the user-scope `~/.qwen/settings.json` whenever possible and avoid persisting credential overrides in any scope. Keeping the provider catalog in user settings prevents merge/override conflicts between project and user scopes and ensures `/auth` and `/model` updates always write back to a consistent scope.
-
-- `/model` and `/auth` persist `model.name` (where applicable) and `security.auth.selectedType` to the closest writable scope that already defines `modelProviders`; otherwise they fall back to the user scope. This keeps workspace/user files in sync with the active provider catalog.
-- Without `modelProviders`, the resolver mixes CLI/env/settings layers, which is fine for single-provider setups but cumbersome when frequently switching. Define provider catalogs whenever multi-model workflows are common so that switches stay atomic, source-attributed, and debuggable.

-
-### Features
-
-- **Native agent experience**: Integrated AI assistant panel within your JetBrains IDE
-- **Agent Control Protocol**: Full support for ACP enabling advanced IDE interactions
-- **Symbol management**: #-mention files to add them to the conversation context
-- **Conversation history**: Access to past conversations within the IDE
-
-### Requirements
-
-- JetBrains IDE with ACP support (IntelliJ IDEA, WebStorm, PyCharm, etc.)
-- Qwen Code CLI installed
-
-### Installation
-
-1. Install Qwen Code CLI:
-
-   ```bash
-   npm install -g @qwen-code/qwen-code
-   ```
-
-2. Open your JetBrains IDE and navigate to AI Chat tool window.
-
-3. Click the 3-dot menu in the upper-right corner and select **Configure ACP Agent** and configure Qwen Code with the following settings:
-
-```json
-{
-  "agent_servers": {
-    "qwen": {
-      "command": "/path/to/qwen",
-      "args": ["--acp"],
-      "env": {}
-    }
-  }
-}
-```

-## Troubleshooting
-
-### Agent not appearing
-
-- Run `qwen --version` in terminal to verify installation
-- Ensure your JetBrains IDE version supports ACP
-- Restart your JetBrains IDE
-
-### Qwen Code not responding

 ## Authentication or login errors
 
-- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY`, `UNABLE_TO_VERIFY_LEAF_SIGNATURE`, or `unable to get local issuer certificate`**
+- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY` or `unable to get local issuer certificate`**
   - **Cause:** You may be on a corporate network with a firewall that intercepts and inspects SSL/TLS traffic. This often requires a custom root CA certificate to be trusted by Node.js.
   - **Solution:** Set the `NODE_EXTRA_CA_CERTS` environment variable to the absolute path of your corporate root CA certificate file.
     - Example: `export NODE_EXTRA_CA_CERTS=/path/to/your/corporate-ca.crt`
 
-- **Error: `Device authorization flow failed: fetch failed`**
-  - **Cause:** Node.js could not reach Qwen OAuth endpoints (often a proxy or SSL/TLS trust issue). When available, Qwen Code will also print the underlying error cause (for example: `UNABLE_TO_VERIFY_LEAF_SIGNATURE`).
-  - **Solution:**
-    - Confirm you can access `https://chat.qwen.ai` from the same machine/network.
-    - If you are behind a proxy, set it via `qwen --proxy <url>` (or the `proxy` setting in `settings.json`).
-    - If your network uses a corporate TLS inspection CA, set `NODE_EXTRA_CA_CERTS` as described above.
-
 - **Issue: Unable to display UI after authentication failure**
   - **Cause:** If authentication fails after selecting an authentication type, the `security.auth.selectedType` setting may be persisted in `settings.json`. On restart, the CLI may get stuck trying to authenticate with the failed auth type and fail to display the UI.
   - **Solution:** Clear the `security.auth.selectedType` configuration item in your `settings.json` file:
