Maven build debug in Eclipse
if you are using Maven 2.0.8+, then it will be very simple, run mvndebug from the console, and connect to it via Remote Debug Java Application with port 8000.
probleme : unit test result are not the same runing with eclipse and maven due ti order of library used by eclipse and maven. In my case the test was success with maven but i want to debug my unit test using eclipse, so the most easy way to debug unit test class with eclipse and runing maven is :
1) mvn -Dtest=MySuperClassTest -Dmaven.surefire.debug test ==> it will listen to the 5005 port (default port)
2) Go to eclipse, open a debug configuration, add a new java remote application and change the port to 5005 and debug
3) of course you must add break point somewhere in the class that you want to debug
The Run/Debug configuration you're using is meant to let you run Maven on your workspace as if from the command line without leaving Eclipse.
Assuming your tests are JUnit based you should be able to debug them by choosing a source folder containing tests with the right button and choose Debug as... -> JUnit tests.
Easiest way I find is to:
Right click project
Debug as -> Maven build ...
In the goals field put -Dmaven.surefire.debug test
In the parameters put a new parameter called forkCount with a value of 0 (previously was forkMode=never but it is deprecated and doesn't work anymore)
Set your breakpoints down and run this configuration and it should hit the breakpoint.
