Invoking JUnit tests from Ant

["Coup, Douglas (MED US)" <do...@siemens.com>]

I'm working with an Ant script that builds a collection of Java plug-ins
and then tries to run some Junit tests against them.

The running of the Junit tests is attempted using the <java> task (<java
classname="org.eclipse.core.launcher.Main"....>).  The -application
parameter is set to "org.eclipse.test.coretestapplication".

When the script gets to this task, I get a
java.lang.NoClassDefFoundError: junit/framework/TestListener error.  The
plugins folder in the target area that the script is using has the
org.junit_3.8.1 plug-in there.  The ANT_HOME environment variable points
to a folder that contains a lib folder with junit-3.8.1.jar in it.  I've
also tried numerous things to get the plug-in's junit.jar into a
location where I thought it would be seen, but with no success.

Does anyone know how to accomplish what I'm trying to do?  I'm fairly
new to Ant, so don't hesitate to include some detail in your response.

I'd use the <junit> task; I dont know what the eclipse testrunner does, 
but it is not ant-aware.

we have just been tweaking it to improve library set up for <junit>, but 
for ant 1.6

-you need junit.jar and ant-junit.jar in ANT_HOME/lib

-If you still get classpath problems, force ant's classpath down into 
the task with something like

       <classpath>
         <pathelement path="${java.class.path}" />
         <pathelement location="${target.jar}" />
       </classpath>
