Maven build debug in Eclipse

Question

I want to debug Eclipse build with tests. I tried to run it by Run > Debug Configurations > Maven Build. In Base directory is my Maven repo directory with pom.xml file, in goals 'clean install'. When I click on debug Eclipse starts build, run tests but it doesn't stops on breakpoints.

Answer 1

Easiest way I find is to:

1. Right click project

2. Debug as -> Maven build ...

3. In the goals field put -Dmaven.surefire.debug test

4. 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.

Answer 2

如果您使用的是 Maven 2.0.8+，那么将非常简单，从控制台运行mvndebug ，并通过端口 8000 的远程调试 Java 应用程序连接到它。

Answer 3

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 .

Answer 4

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
