We are using filtered testResources in JUnit-tests that are usually executed by the maven surefire plugin. That is, the pom contains a section

  <build>
    <testResources>
      <testResource>
        <directory>src/test/resources</directory>
        <filtering>true</filtering>
      </testResource>
    </testResources>
    ...

How can I run such JUnit-tests in the debugger? If I execute the tests in eclipse the tests fail since the test resources are not filtered. If the filtered test resources would be written somewhere into the target directory, I could just use this as an additional source path - but this is not the case. If I try to run the maven build in eclipse with Debug As / maven test , the build does not stop in the breakpoints. Any other ideas?
