Please add an option to the 'changes-check' goal to allow skipping release date checks of snapshot versions.

Patch adding a 'skipSnapshots' parameter to the 'changes-check' goal.

What about timestamp snapshots? Those don't have -SNAPSHOT in their name anywhere.

The need for such an option indicates to me that you might not be using this goal the way it was intended. For me this goal is supposed to be used in a release profile or something similar, so that it is only run prior to a release being made.

What is your use case?

I would like to be able to enable the release profile when building snapshots (e.g. for testing the release build or for deploying snapshots publicly). Just like 'mvn deploy' automatically chooses a repository to upload to based on the kind of artifact acted upon, I would like to avoid having to invoke maven differently based on the kind of artifact acted upon when enabling the release profile. The current behavior of the 'changes-check' goal makes this impossible, since it will fail the build when building a snapshot for which no matching release version is found in the 'changes.xml' file or for which no release date is found which makes no sense for snapshots, IMHO. Therefore, the goal should automatically skip itself, when building a snapshot.

I would commit this if I could find the recipe for looking a a timestamp snapshot version and determining that it is, in fact, a snapshot version. It has to be in maven core somewhere.

Updated patch to use 'ArtifactUtils.isSnapshot'. I am not sure if method 'ReleaseUtils.getLatestRelease' also needs updating to support timestamp snapshot version.
