This might also arise due to the presence of circular dependency in your eclipse workspace.Gae Runtime Manager.ensure Gae Runtime With Sdk(Gae Runtime Manager.java:55) at com.google.appengine.maven.Gae Facet Gae Facet(Gae Facet Manager.java:59) at com.google.appengine.maven.(you can also remove the -clean tag from the ini file so it doesn't clean everytime you start it) Hope this helps someone.The root issue in my case was a file conflict in the .settings folder.File.exists() method, particularly because the code already had successfully done the same thing in a previous method with the same variable, then called File() without problem.
