Subject Re: Setting classpath for optional task
Date Fri, 02 Mar 2001 22:25:10 GMT
I've try this but I still get a junit/framework/TestListener class not
found error.  Note that my junit.jar is not in the same ant's lib
directory.  I'm using JUnit 3.5 and Ant 1.3b3.  Here is the stack trace:

/home/wlee/smi/SendmailGUI/dist/turbine/webapps/ListEditor/WEB-INF/build/build.xml:210:
Could not create task of type: junit due to

The build file would work if I specify the junit.jar in the
LOCALCLASSPATH variable in the script that invokes Ant.  

Can anyone tell me why?
