When to use this skill

ALWAYS use this skill when the user mentions:

• Searching for Maven dependencies or components
• Finding Maven coordinates (groupId, artifactId, version)
• Checking component versions or version history
• Retrieving Maven artifacts (JAR, POM, sources, Javadoc)
• Verifying Maven dependency coordinates
• Analyzing dependency trees or transitive dependencies
• Working with Maven Central Repository
• Any request related to Maven components, libraries, or dependencies

Trigger phrases include:

• "查找 Maven 依赖" (find Maven dependency), "搜索 Maven 组件" (search Maven component)
• "Maven 坐标" (Maven coordinates), "groupId" (groupId), "artifactId" (artifactId)
• "Maven 版本" (Maven version), "最新版本" (latest version), "版本历史" (version history)
• "Maven Central" (Maven Central), "Maven 仓库" (Maven repository)
• "下载 Maven 依赖" (download Maven dependency), "获取 POM 文件" (get POM file)
• "依赖树" (dependency tree), "传递依赖" (transitive dependencies)
• Any mention of "Maven", "dependency", "artifact", "repository", "coordinates"

How to use this skill

CRITICAL: This skill should be triggered when the user needs to search, retrieve, or work with Maven components from Maven Central Repository.

Trigger this skill when you see:

• User says "查找 Maven 依赖" (find Maven dependency), "搜索 Maven 组件" (search Maven component)
• User needs Maven coordinates (groupId, artifactId, version)
• User wants to check component versions or retrieve artifacts
• User mentions Maven Central Repository or Maven dependencies
• User needs to analyze dependencies or verify coordinates

To search for Maven components:

1. Identify the search type from the user's request:

   • Search by name → Use Maven Central Search API
   • Get specific version → Use direct repository URL
   • Check latest version → Query maven-metadata.xml
   • Analyze dependencies → Parse POM file
   • Download artifact → Use direct download URL

2. Load the appropriate example file from the examples/ directory:

   • examples/search-by-name.md - Search components by name or keywords
   • examples/search-by-coordinates.md - Search by groupId and artifactId
   • examples/get-version-info.md - Get version information and history
   • examples/download-artifact.md - Download JAR, POM, sources, or Javadoc
   • examples/analyze-dependencies.md - Analyze dependency tree
   • examples/verify-coordinates.md - Verify Maven coordinates validity

3. Follow the specific instructions in that example file for API endpoints, parameters, and best practices

4. Use Maven Central Repository API:

   Search API (https://search.maven.org/solrsearch/select):

   • Query parameter: q - Search query (e.g., g:com.google.guava AND a:guava)
   • Rows parameter: rows - Number of results (default: 20, max: 200)
   • Start parameter: start - Pagination offset
   • Core parameter: core - Search core (default: gav)

   Direct Repository Access (https://repo1.maven.org/maven2/):

   • Path format: {groupId}/{artifactId}/{version}/{artifactId}-{version}.{extension}
   • GroupId path: Replace dots with slashes (e.g., com.google.guava → com/google/guava)
   • Metadata: maven-metadata.xml for version information
   • POM file: {artifactId}-{version}.pom
   • JAR file: {artifactId}-{version}.jar
   • Sources: {artifactId}-{version}-sources.jar
   • Javadoc: {artifactId}-{version}-javadoc.jar

5. Construct the appropriate URL:

   Search Example:

   https://search.maven.org/solrsearch/select?q=g:com.google.guava+AND+a:guava&rows=20&wt=json
   

   Direct Access Example:

   https://repo1.maven.org/maven2/com/google/guava/guava/maven-metadata.xml
   https://repo1.maven.org/maven2/com/google/guava/guava/33.0.0/guava-33.0.0.pom
   https://repo1.maven.org/maven2/com/google/guava/guava/33.0.0/guava-33.0.0.jar
   

6. Parse and format the results:

   • Extract relevant information (groupId, artifactId, version, description)
   • Format coordinates in standard Maven format: groupId:artifactId:version
   • Present results in a clear, structured format
   • Include download links and metadata when relevant

7. Validate coordinates:

   • Verify groupId format (should be reverse domain notation)
   • Check artifactId format (should be lowercase, hyphen-separated)
   • Validate version format (semantic versioning preferred)
   • Confirm artifact exists before providing download links

Output Format Requirements:

• Always provide Maven coordinates in standard format: groupId:artifactId:version
• Include direct download URLs when relevant
• Format search results in a clear, structured table or list
• Provide metadata information (description, repository, last updated) when available
• Include version information and release dates when querying versions

Maven Central Repository Structure

Repository Base URL

• Primary: https://repo1.maven.org/maven2/
• Search API: https://search.maven.org/solrsearch/select
• Alternative mirrors: Available for different regions

Path Structure

{groupId}/{artifactId}/{version}/{artifactId}-{version}.{extension}

Example:

com/google/guava/guava/33.0.0/guava-33.0.0.jar

Available Artifacts

• POM: {artifactId}-{version}.pom - Project Object Model file
• JAR: {artifactId}-{version}.jar - Compiled Java classes
• Sources: {artifactId}-{version}-sources.jar - Source code
• Javadoc: {artifactId}-{version}-javadoc.jar - API documentation
• Metadata: maven-metadata.xml - Version and release information

Search API Parameters

Query Syntax

• GroupId search: g:com.google.guava
• ArtifactId search: a:guava
• Version search: v:33.0.0
• Combined search: g:com.google.guava AND a:guava
• Text search: guava (searches in groupId, artifactId, and description)

Response Format

• JSON: wt=json (default)
• XML: wt=xml
• Java properties: wt=javabin

Pagination

• rows: Number of results per page (default: 20, max: 200)
• start: Offset for pagination (default: 0)

Best Practices

1. Always verify coordinates: Check that groupId, artifactId, and version exist before use
2. Use latest stable versions: Prefer RELEASE versions over SNAPSHOT versions
3. Check version metadata: Query maven-metadata.xml for latest version information
4. Validate before download: Verify artifact exists before providing download links
5. Include checksums: When available, provide SHA-1 and MD5 checksums for verification
6. Format coordinates correctly: Always use standard Maven format groupId:artifactId:version
7. Provide context: Include description, repository information, and last updated date when available

Common Tasks

Task 1: Search by Name

Use the Search API with text query to find components by name or keywords.

Example:

GET https://search.maven.org/solrsearch/select?q=guava&rows=20&wt=json

Task 2: Search by Coordinates

Use the Search API with groupId and artifactId to find specific components.

Example:

GET https://search.maven.org/solrsearch/select?q=g:com.google.guava+AND+a:guava&rows=20&wt=json

Task 3: Get Version Information

Query maven-metadata.xml to get all available versions and latest version.

Example:

GET https://repo1.maven.org/maven2/com/google/guava/guava/maven-metadata.xml

Task 4: Download Artifact

Construct direct download URL for specific artifact.

Example:

GET https://repo1.maven.org/maven2/com/google/guava/guava/33.0.0/guava-33.0.0.jar

Task 5: Analyze Dependencies

Download and parse POM file to extract dependency information.

Example:

GET https://repo1.maven.org/maven2/com/google/guava/guava/33.0.0/guava-33.0.0.pom
