Android Studio update corrupted gradle

Question

So I downloaded a .zip from the latest 2.0 version (here: http://tools.android.com/download/studio/builds/2-0 ) because Android Studio didn't allow me to download a patch and automatically update itself. And then pasted the .zip folder tree into my installation directory.

Now I have this gradle error:

Error:org.gradle.tooling.BuildActionExecuter.withCancellationToken(Lorg/gradle/tooling/CancellationToken;)Lorg/gradle/tooling/BuildActionExecuter;

Please tell me there's a way to fix this without reinstalling.

Answer 1

Please be careful and close Android Studio ==>

• go to :

   android-studio/plugins/gradle/lib 

• move all jar files starting with gradle* to other folder in your desktop per example ==> remove them from lib folder

• Start Android Studio again and rebuild/refresh.

update:

from @alex-newman (first comment):

There were 2 versions of gradle* inside: android-studio/gradle/gradle-2.10. I deleted the 2.8 leftovers and it got fixed.
