In case you have an older Java 6 application and want to switch to Java 7 code with goodies like diamond operator and multi-type exceptions:
touch .openshift/markers/java7
git add .openshift/markers/java7
Also make sure you don't have it ignored in .gitignore like I had.
Then in pom.xml
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.0</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
Then git push, and you're done.
