Hi,
There was a bug reported on a the optional junit task "junit task error
message"
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=3978
This bug report, gives a workaround that I have applied to my project, i.e. load the
junit.jar and the ant-optional.jar is the same classloader then
declare junit task
with taskdef with a classpath that includes junit and ant-optional.jar.
When I lauched the ant build script on command line, it works perfectly.
However when I launch the ant build script from IDEA build 612, I still get the error
reported is the previous bug report.

Why the behaviour is different from the command line ?
Is there a workaround ?
"This is expected behaviour. The junit.jar has to be in the same classloader
that the junit task is in. This means that you either have to place junit.jar
in $ANT_HOME/lib or remove optional.jar from $ANT_HOME/lib and use <taskdef
..> to define it with a classpath that includes junit and optional.jar" Peter Donald,
