I’m having problems with a java.lang.NoClassDefFoundError when trying to run my JUnit tests from ANT using the runtestsreport task in thefollowing build.xml; I know the other tasks work, it’s just the actual running of the tests that’s the problem.
I’ve tried lots of adjustments based on questions posted on here but I can’t fix it; what I really need is a dev to pair with but they’ve all gone home for the day.
Can anyone help?
The build.xml file is
<property name="build" location="C:\<path on my machine>\workspace\ESS\build"/>
<property name="testsbuild" location="C:\<path on my machine>\workspace\ESS\build\esstestapp\tests"/>

I get this error (and this type of error for each test class)
Credentials (wrong name: esstestapp/tests/Credentials)

I’ve ran ant in -verbose mode to check the classpath out but I can’t see the problem (even though I know that it’s staring me in the face)

Any eyes over this to help me get the tests running would be greatly appreciated.
Thanks

Update
I observe that if I edit tests.classpath to remove the following 2 lines then the error I see switches to a ClassNotFound which makes sense as it has no references to the .jar files that contain the classes.
<fileset dir="${testsbuild}/jar" includes="**/*.jar"/>
<fileset dir="${frameworkbuild}/jar" includes="**/*.jar"/>
With the above 2 lines present in the tests.classpath is happily finds them but with the wrong name and it’s that error I don’t know how to fix.
Problem caused by the following jar command:
The testsbuild property should be set to
Explanation
The file Credentials.class was compiled as the class esstestapp.tests.Credentials. It needs to be found on the classpath as the file:
esstestapp/tests/Credentials.class
