I'll just note that any of extension, classifier and compatVersion parts can be
empty string so you can see provides such as:


mvn(groupId:artifactId::classifier:) = version

Note that if last colon was omitted the classifier would be considered as a
version:

mvn(groupId:artifactId::version) = version

But provides/requires generators will always use the shorter version of 
mvn(groupId:artifactId:version) = version

This is good to know if you need to specify extension/classifier for some of the
scripts such as add_maven_depmap:

%add_maven_depmap gId:aId:war:version <path_to_war>

Following usage would be incorrect because last part (war) would be considered
as a version:

%add_maven_depmap gId:aId:war <path_to_war>
