I continue to get this error. I have reinstalled Android Studio and even copied a functioning installation from another user's Mac desktop without changing the result. I am using OS X 10.7.5
Failed to import Gradle project: Cause: org.apache.commons.lang.ObjectUtils.compare(Ljava/lang/Comparable;Ljava/lang/Comparable;)I
I see others have had similar problems with Gradle but not with this error.
