所以我一直在尝试编译我的代码，我收到以下错误：
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)
我手动将CurrentSDK符号链接强制转换为java 1.7：
6003088f811e:~ jvy234$ which java
/usr/bin/java
6003088f811e:~ jvy234$ ls -ltr /usr/bin/java

当我转到Java的Preferences面板时，我看到安装了Java 1.7_80。我该怎么做才能使它使用JDK 1.7？
