antrun cannot run junit task

[Russell Gold-3]

I am converting a convoluted ant build to maven. It has a large number of functional tests, mostly built on either TestNG or the now-deceased author's private framework, but some on junit. I am running the tests via the antrun plugin, but it when it hits a junit task, it fails with:

Could not load class (org.apache.tools.ant.taskdefs.optional.junit.JunitTask) for type junit

I have confirmed that the ant-junit jar is in the classpath (although I'd have expected all ant task jars to be there automatically). What do I need to do to get this to work? And no, I cannot simply move these tests to let maven run them normally - the test build is a horrible mess.

Being on the classpath is not necessarily sufficient. Did you simply
declare this as a dependency (scope=test) in the project? Or did you
add it to the PLUGIN classpath via <plugin><dependencies><dependency>
which is what is required for this to work?

Aha! Thank you! I searched the antrun plugin docs for info, but it's not there. What would it take for this to be added as a FAQ? It seems other people have been running into the same problem.

I hate to say RTFM but it is appropriate in this case...
