Ant: java.lang.NoClassDefFoundError: org/apache/tools/ant/taskdefs/optional/junit/JUnitTestRunner [message #178093]

After installing M6, I get these error when trying to run ant build scripts
that include the junit task.

[junit] java.lang.NoClassDefFoundError:
org/apache/tools/ant/taskdefs/optional/junit/JUnitTestRunner
[junit] Exception in thread "main

I checked to see the the ANT classpath includes the optional.jar that comes
with the M6 install. It does.

What is the fixed for this?

The following might help:select the JRE page (in the wizard that comes
up when launching your script) and select "Run in the same JRE as the
workspace".

Is there any way to avoid this error while using an external JDK? I have
to increase the heap size for my ant script, but I still get the
JUnitTestRunner not found error.

Likely your classpath is not sufficient for the Junit task. If the buildfile
works from the commandline and does not work within Eclipse, please log a
bug report against platform Ant and I will have a look.

Note to increase the heap size when running in the same VM as Eclipse start
eclipse specifying -vmArgs. Something like:
-vmArgs -Xmx450M -Xms250M

I managed to get the task to work using the internal VM, by specifying
those types of args. Using the external VM, though, never worked.

I suspect that the optional.jar file isn't being handed off properly to
the external VM, but I have no real way to verify that.
