Add properties for source+target when used by maven-invoker-plugin.
Right now plugins are compiled with source/target 1.5, which is not supported by JDK9. However, we can test if 1.5 compiled plugins still work with a JDK9 runtime environment. You'll execute it like this:
mvn verify -Prun-its -Dinvoker.javaHome=%JAVA9_HOME% -Dinvoker.maven.compiler.source=1.6 -Dinvoker.maven.compiler.target=1.6
