Comment (by iwakeh):

 In order not to forget anything before committing the following task could
 be added:
 {{{
   <target name="pre-commit" depends="test,checks,coverage" >
     <fail if="wrong-jvm"
           message="Please run with Java ${source-and-target-java-version}
 instead of ${java.version}.">
     </fail>
   </target>
 }}}

 With this one 'only' needs to run one task before committing.
