Missing class for regex
I'm trying to use the <propertyregex> task from ant-contrib. It works
fine when I call my ant build script directly, but when I call it
indirectly within a Maven/Eclipse environment, I get this error message:
build.xml:67: No supported regular expression matcher found:
java.lang.ClassNotFoundException:
org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp
I'm guessing that this is a classpath problem, and Maven isn't
automatically including all the libs it needs, so I need to include them
manually. No problem -- I found the jar that contains the class,
ant-nodeps.jar, and put it on the classpath. (And confirmed that it's
there.)
Still getting the same error, though. What's wrong?

Figured it out. The trick is to add the dependency to the plugin, not to
the main dependencies section of the pom file. It needs "plugin" scope.
