Description

Currently warnings will be emitted when there are expressions in versions, a few exceptions should be deemed valid to make continuous delivery easier. The use case is to allow easy versioning of an entire multi-module build that can take a version from an external source like SCM. These are the types of exceptions that will be allowed:

1.0.0.${changelist}
1.0.0.${revision}
1.0.0.${sha1}

When a whole build is versioned like this we can avoid churning the POMs in the SCM which makes it a lot easier to see the actual changes in the project. Not a complete solution for continuous delivery but is a step in the right direction and doesn't interfere with currently behavior as it is currently allowed, just warned against.
