Building time-stamped snapshots with multiproject:install-snapshot (same applies to multiproject:deploy-snapshot) results in unreliable versions if you use versioned snapshots. The install-snapshot goal will build artifacts without the version information using just -SNAPSHOT and renames them to a timed version, but any dependent artifact will use later on -<version>-SNAPSHOT in its dependencies, that were not even build and may be downloaded in an buggy version from an internal repo.

Example (cut down to the interesting parts):

====== %< =======

The build did neither create one single time-stamp (optimal) nor use the time-stamed versions (quite optimal) nor the created snapshots (still valid), but the uncontrolled and downloaded versioned snapshots and they were even included and delivered in the war.

The behaviour could also be changed to create time-stamped snapshots, that keep the version and just replace the -SNAPSHOT part. This would also allow time-stamed snapshots from different branches of a project.

Jörg
