   • Maven.MavenHome: Path to your Maven installation (optional).

Usage

Project Detection

VSCode automatically detects Maven projects by looking for a pom.xml file in the workspace root. Once detected, the extension provides additional features and context menus for Maven commands.

Quick Actions

You can right-click on the pom.xml file to access quick actions like ‘Add Dependency’, ‘Open User Settings’, ‘Run Maven Build’, etc.

Dependency Management

The extension provides an intuitive UI to manage dependencies. You can view, add, and remove dependencies directly from the VSCode interface.

Code Completion

The extension enhances code completion for Maven projects, providing suggestions for classes, methods, and other artifacts from your project’s dependencies.

Build Automation

You can easily run Maven build commands like clean, install, package, etc., directly from VSCode. The extension also provides feedback and output in the integrated terminal.

Advanced Tips

1. Customizing Commands: You can customize Maven commands by creating a .vscode/tasks.json file in your project’s root directory. This allows you to define new tasks or modify existing ones to suit your needs.
2. Using Wrapper: If you’re working in a multi-platform environment, consider using the Maven Wrapper (mvnw) instead of a globally installed Maven. The wrapper ensures consistency and portability by downloading and using the correct Maven version for your project.
3. Debugging: If you encounter issues with the extension, try disabling other extensions to see if they’re conflicting. You can also check the VSCode output panel for any error messages or logs related to the Maven extension.
