[INFO] [ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.24.0:validate-version (default-validate-version) on project jdt-core: Maven version 2.0.0 must have -SNAPSHOT qualifier for SNAPSHOT builds

So trying to push release 2.0.0, besides a very messy package setup that I'll fix later (ie it asked me more than the typical once for version number), I cannot get through release:prepare. It fails with the error above. Any ideas?
