To deploy to Google app engine (GAE)
- It is important to indicate an available GAE SDK (usually behind the official)
- When following the instructions in http://code.google.com/p/playn/wiki/GettingStarted, it may be necessary to run mvn install first prior to the mvn -f html/pom.xml gae:run

mvn compile
mvn install

then repeat this for react and tripleplay
to use these development snapshots into your project, make sure to update the playn version in the pom.xml
you can check that the latest version is available by looking into your local repo like so:

cd ~/.m2
find . -name '*playn*'
