Maven: debugging

If you've ever been in the situation that you'd need to debug maven build, these are the options that could help.

Debugging maven run

If you need to debug maven plugins run itself use instead of standard:

mvn <your sfuff>

the debug one:

mvnDebug <your sfuff>

It should tell you it's waiting for connection, in a way like this:

Preparing to Execute Maven in Debug Mode
Listening for transport dt_socket at address: 8000

Afterwards use your preffered way to connect to socket 8000 via remote debugger. (For eclipse steps can be found here, or googled)

Debugging test execution

If you need to debug maven-surefire-plugin run use following:

mvn -Dmaven.surefire.debug test

It would wait for connection, in a way like this:

Listening for transport dt_socket at address: 5005

Afterwards use your preffered way to connect to socket 5005 via remote debugger. (For eclipse steps can be found here, or googled)
Easy, isn't it?
