title: App Engine and Eclipse on Ubuntu Linux 12.10
body: <p>I updated Ubuntu from 12.04 to 12.10.</p>
  
  <p>It upgraded my Eclipse too, from 3.7 to 3.8.</p>
  
  <p>Turns out, Google App Engine doesn't have a plug in for 3.8. Just 3.7 and 4.2.</p>
  
  <p>So I upgraded Eclipse to 4.2.</p>
  
  <p>When I upload my project, it says it can't because of the java-7 flags. I found a post on here that described how I might change the flag, but it wouldn't matter because I'm not a "Trusted Tester" so they wouldn't allow it yet anyways.</p>
  
  <p>I tried to change the Project's build path to include OpenJDK 6 and a compiler level of 1.6</p>
  
  <p>I get this project error "Java compiler level does not match the version of the installed Java project facet."</p>
  
  <p>I've looked it up, and found a message on StackOverflow, but I can't figure out what facets I'm using or if that solution even applies.</p>
  
  <p>Is it possible to use Eclipse 4.2 and the App Engine 1.7.4 to upload a project to App Engine? </p>
  
  <p>How do I get it to use Java6?</p>
