I used antcallback from antcontrib in my Buildfile:

        <antcallback target=3D"junittests" inheritall=3D"false" =
return=3D"dope.test.failed">
          <param name=3D"cvs.project" value=3D"@{dope.modul}" />
          <param name=3D"dope.buildtime" value=3D"${dope.buildtime}" />
        </antcallback>

So I got back if one of my tests failed.

antFetch is the same f=FCr calling external Buildfiles.

Use http://sourceforge.net/project/showfiles.php?group_id=3D36177 to get =
antcontrib.

  the ant-contrib extensions on sourceforge have a task to get results =

No, it isnt

1. you should have a common build file that is pulled in to the main =
file with <import>; it can do the result output

2. you can create a test.failed file for every project
(build/results/tests.${ant.project.name}.failed) if -and only  if- the =
tests for that project failed.

3. then, the toplevel file uses <available> to look for any file =
matching that pattern, which implies that the test failed.
