--- Important Note:
-
-The gae-maven-plugin requires a locally extracted copy of the App
-Engine SDK in order to run. The gae:unpack goal can do this for you
-automatically, by downloading and extracting the contents of
-com.google.appengine:appengine-java-sdk:zip into your local maven
-repository. The mobilewebapp POM should take care of this, as it
-includes the gae:unpack goal. However, if you have gae.home set in
-your settings.xml, it won't work properly. The gae:unpack goal will
-only work correctly if sdkDir / gae.home are not set. For more info,
-see this bug report
