Delegate to the maven-tycho-plugin to set version of all subprojects. It maintains the POM and
MANIFEST version numbers in sync. This script runs maven on each parent project.

Note:
    Use only numeric versions (do not specify -SNAPSHOT at the end, it is added by this script).

Example:
    set-versions.sh 3.0.3

    This sets the pom version to 3.0.3-SNAPSHOT and the Bundle-Version to 3.0.3.qualifier
