Description

I want to remove the version from the file names, but want to keep the classifier. This is not currently possible, because you cannot make characters optional in outputFileNameMapping.

If you use this configuration:

@{artifactId}@-@{version}@-@{classifier}@.@{extension}@

then jar files without a classifier will get an extra "-" in it.
maven-test-lib-1.0.jar becomes maven-test-lib-.jar

We want to use a configuration like this:

@{artifactId}@-@{version}@[-@{classifier}@].@{extension}@

so that the "-classifier" is only applied if there is a classifier.
maven-test-lib-1.0.jar should now become maven-test-lib.jar

To fix this I need to change the regular expressions used by RegexBasedInterpolator (from plexus interpolation) in MappingUtils.java:66 but don't know how? Is it even possible?
