I'm getting following error when trying to compile my project in Android Studio:
Gradle: error: diamond operator is not supported in -source 1.6
I have 1.7 set as target in all project preferences I've found. Also the path displayed in project SDK's under 1.7 SDK is correct path to java 1.7 installation.
Even when I run java -version in terminal, it tells me I'm running on java 1.7.
I have tried to set JAVA_HOME env variable to this:
/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home
The error does not go away. How do I eliminate the error?

Java 7 support was added at build tools 19. You can now use features like the diamond operator, multi-catch, try-with-resources, strings in switches, etc. Add the following to your
build.gradle
.Gradle 1.7+, Android gradle plugin 0.6.+ are required.
Note, that only try with resources require
minSdkVersion
19. Other features works on previous platforms.Link to android gradle plugin user guide
