Not sure if the JDK change is the true cause of the problem. Could you try with the latest m7 snapshot (see recent announcement)? ---

Same error with gradle-1.0-milestone-7-20111220000018+0100. The error happens when Gradle tries to resolve the first project dependency in a multi module java project. After a quick grep over the sources I suppose that something fails during dynamic code generation in AsmBackedClassGenerator or AsmBackedEmptyScriptGenerator under Jdk 1.7 because there the “\_Decorated” is added to type names. ---

It’s normal that \_Decorated is added to type names. I just tested with Oracle JDK 1.7.0\_01 on Windows and all went fine. I can even build Gradle itself. Will try 1.7.0\_02. Which OS and JDK do you use? ---

I get this too, but only when switching around. Do you use the Gradle daemon? This works for me (on Win7): 1. change JAVA\_HOME to JDK 7u1 or 7u2 2. delete projectDir/.gradle 3. delete ~/.gradle/caches (you don’t need to delete sub dirs starting with “artifacts”) 4. run a clean build without daemon This way I can build Gradle itself with JDK 7u1 and 7u2. ---

Cleaning the gradle directories did the trick. Thanks for the quick response. ---

We should get smarter at invalidating the caches, but for now I’m marking this as solved. ---

Hi Peter, I am having almost the same issue as Gunther did but today (26/11/12); PATH: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0;C:\Program Files\QuickTime\QTSystem;%JAVA\_HOME%\bin JAVA\_HOME: C:\Program Files\Java\jdk1.7.0\_09 Windows 7 Professional Patched Followed the instructions exactly on [http://code.google.com/p/android-apktool/wiki/BuildApktool](http://code.google.com/p/android-apktool/wiki/BuildApktool) I followed the instructions above, modified JAVA\_HOME to JDK 7u1 and 7u2 =\> immediate failure. Changed JAVA\_HOME back to what it is not, deleted the .\gradle, the project\_dir, .\Apktool etc, start again. Result in Gist below. git://gist.github.com/4146669.git Cheers Mashed Updata
