JDK在Mac OSX 10.10.2上仍指向1.6

Question

So I have been trying to compile my code and I get the following error:

Information:Using javac 1.7.0_80-ea to compile java sources
Information:java: Errors occurred while compiling module 'DataRegistry'
Information:4/8/15, 9:48 AM - Compilation completed with 14 errors and 0 warnings in 2 sec
    /Users/jvy234/Documents/workspace/dataregistry/src/main/java/com/capitalone/hub/registry/controller/SandboxController.java
    Error:(169, 43) java: diamond operator is not supported in -source 1.6
      (use -source 7 or higher to enable diamond operator)

I manually forced the CurrentSDK symlink to java 1.7:

6003088f811e:~ jvy234$ which java
/usr/bin/java
6003088f811e:~ jvy234$ ls -ltr /usr/bin/java

lrwxr-xr-x  1 root  wheel   59 Apr  8 09:43 CurrentJDK -> /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/

When I go to my Preferences panel for Java I see Java 1.7_80 installed. What can I do to make it use JDK 1.7 ?

You can change the jdk used to compile your project in File/Project Structure/SDKs/Java SDK (see here ).

If you wish to change the compiler of your entire workspace, you can change the compiler used in File/Settings/Build, Execution, Deployment/Compiler/Java Compiler (see this doc page ). If you still get the same error message, you can pass -source 7 in the javac options.
