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

!!!!
!!!! Some files still need to be updated manually:
!!!!     <parent> tag of pom.xml in org.scala-ide.{sdt.build,build-toolchain,p2-toolchain}
!!!!     */resources/{feature,pom}.xml
!!!!     */resources/META-INF/MANIFEST-*.MF
!!!!
!!!! This can be done with the following command:
!!!!
!!!!   ag "<old-version>" | awk -F ':' '{print $1}' | xargs sed -i '' 's/<old-version>/<new-version>/'
!!!!
!!!! where <old-version> is the version of the previous release and <new-version> the version of the next release.
!!!! ag is a tool similar to grep or ack, it is also called "The Silver Searcher": https://github.com/ggreer/the_silver_searcher
!!!! In constract to grep or ack, ag considers the .gitignore files and therefore makes updating the relevant versions easier.
