Can I use this skill with IDEs like IntelliJ or VS Code?

Yes, while it provides a specialized workflow for jdb in the terminal, you can attach any JDWP-compliant debugger to the port opened by the skill.

How do I handle multi-module Java projects?

The skill supports a --module flag to target specific sub-projects, ensuring that Maven only runs and debugs the relevant code.

What is the main benefit of the Maven Surefire Debugger skill?

It simplifies the complex process of setting up a suspended JVM for Maven tests, allowing you to attach a debugger to the exact moment a test starts.

Do I attach the debugger to the Maven process itself?

No, you attach to the forked JVM that Maven Surefire launches to run the tests, which prevents the debugger from getting stuck in Maven's internal processes.

What should I do if jdb says 'No frames on the current call stack'?

This is normal when the JVM starts suspended; simply set your desired breakpoints or exception catches and use the 'cont' command to begin execution.

Seguridad y Pruebas

Debugs Maven Surefire unit tests by running them in JDWP 'wait for debugger' mode and attaching via jdb or IDEs.

The Maven Surefire Debugger skill streamlines the process of troubleshooting failing Java unit tests by automating the setup of JDWP remote debugging. It executes Maven tests in a suspended state, allowing developers to attach jdb, IntelliJ, or VS Code to the forked test JVM to step through code, inspect variables, and catch assertions. This is particularly useful in headless or agent-based environments where command-line debugging is essential for resolving complex test failures or race conditions in multi-module projects.
