Description

running ./gradlew build on the current head without the indy option lets the :javadoc target fail due to java 7 code (diamond operator) in groovy reflection code and the fact that gradle/docs.gradle sets source = rootProject.useIndy()?'1.7':'1.6'.

./gradlew -Pindy=true javadoc works, ./gradlew -Pindy=false javadoc produces the following error

:javadocD:\Projekte\Groovy\groovy\src\main\org\codehaus\groovy\reflection\CachedClass.java:89: error: diamond operator is not supported in -source 1.6
            final ArrayList<AccessibleObject> ret = new ArrayList<>(aoa.length);
                                                                  ^
  (use -source 7 or higher to enable diamond operator)
