How to debug a maven project in Eclipse?

Question

I am trying to debug following maven project in Eclipse: https://code.google.com/p/cloudscale/

I followed the instructions of RickHigh (found here https://stackoverflow.com/a/19986408/3014213 ) and when I write mvnDebug exec:exec in Terminal the lines

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

appears and after starting the Remote Java Application in Eclipse, the project is started BUT it does not hold on breakpoints...

Any ideas, what could go wrong?

Answer 1

When you install m2e plugin in Eclipse, it will show you a link in Console view to automatically connect debugger (ie create remote debugger launch configuration) to your process when it spills "Listening for transport dt_socket at address: 8000" message to the console. So, your debugger is basically one click away.

Answer 2

The debugger may be connected to the wrong JVM - not the one created by exec:exec . Try remote debugging like here: https://stackoverflow.com/a/22367089/1878731
