Build fails using Java 7

[af608]

Works now with Java 8, but fails with Java 7:

Execution failed for task ':app:compileDebugJavaWithJavac'.
java.lang.EnumConstantNotPresentException: javax.lang.model.SourceVersion.RELEASE_8

I was trying the newest version with

compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
as well as a JDK7 to compile my Android app. It compiled with no errors.
Could you please provide further information about your project setup?
