Choose Java 7 JRE to run App Engine Dev Server with Cloud Tools for Eclipse

Question

I try to run my maven App Engine project using Google Cloud Tools for Eclipse. Using "Run As > App Engine" as suggested in the docs results in the project being run in a Java 8 runtime (same as Eclipse uses). App Engine only supports Java 7. The only execution environment in the Eclipse installation is a Java 7 JRE.

How can I make the Dev Server use the Java 7 JRE?

Edit

Upgrading to Cloud Tools for Eclipse 1.1 did the trick; it now looks for the JVM that is configured for the project.

Answer 1

1. First check if you have Java 7 installed on your system and environment variable are set correctly
2. Now coming to the Eclipse, Right Click On Your Project -> Java Compiler -> Set Compiler Compliance Level to 1.7
3. You can apply this setting for all the future projects by doing this 'Window' Menu -> Java -> Compiler -> Set Compiler Compliance Level to 1.7

Hope this helps. :)
