Bamboo Ant Task fails when running junit task

问题:

In my current project I'm using junit tests. Runing my ant file on my local pc produces my Test Report as expected, but when bamboo tries to run my tests, it produces the following output.

Whats my mistake?

SimplerTest.java

import static org.junit.Assert.*;

import org.junit.Test;

public class SimplerTest {


@Test
public void dummerTest()
{
    assertTrue(true);
}
}

Local Output:

Buildfile: C:\Users\jussi\git\kingdom-builder-repository\build.xml

compile-test:
[javac] Compiling 1 source file to C:\Users\jussi\git\kingdom-builder-repository\bin

junit:

Thanks for the verbose Ant output.

It appears you are running Ant 1.9.0 on your Bamboo server. There is a known issue (bug 54835 - Classpath use seems to be broken in junit ant task?) in the Ant bug tracker, which was started by the poster of a similar question on SO: "Class not found with Ant, Ivy and JUnit - error in build.xml?":

That question didn't have a clear / short answer, but the bug report does:

It looks like the class search is being delegated to the System's classloader rather than being handled by the Ant Classloader (the system Classloader has no knoweldge of JUnit since JUnit isn't on the core Ant Classpath, but is added to the JUnit task by Ivy). Given some JUnit classes must have already been loaded to have reached this point, the Ant Classloader can see the JUnit jars loaded by Ivy, but the Split Classloader seems to be delegating incorrectly when trying to load classes used by the JUnit Runner.

In other words: Ant's JUnit task has bugs and won't work, and I think you are affected by this specific bug. The bug report goes on and lists these fixes / workarounds:

• Wait for Ant 1.9.1 (the bug report is marked as fixed and the release can be expected very soon)
• Copy your JUnit JAR into your ANTLIB directory and keep using Ant 1.9.0. This is not so good if you want to mix JUnit versions, but it should work if all you use is 4.10 or so.
• Use Ant 1.8.4
