Hi Fabian. Thank you very much for the new logs. I would still like to understand why `org.gradle.internal.hash.FileHasher` can’t be resolved for your project, but it doesn’t really matter for the problem we are trying to solve (it would be great if you could provide me with a full stacktrace). The `sha1`s of the files are sufficient. It seems like the Android plugin jars shipped with Android studio are different from the ones in your Gradle repository cache. E.g. `/.gradle/caches/jars-3/d15c489eefc089360ed43525f2f8dd09/gradle-3.0.0-beta6.jar` is different to `/.gradle/caches/modules-2/files-2.1/com.android.tools.build/gradle/3.0.0-beta6/948b8c05b40b5f607a49d58e7c66a95faa61134f/gradle-3.0.0-beta6.jar`. These jars should actually be the same. Please have a look at the diff of these to files to get an understanding what happened there. I think we cannot do something in Gradle to fix this problem but the Android plugin/Android Studio needs to be fixed to either - not ship a file repository - ship the same artifacts in the file repository as are uploaded in the public maven repository. I would prefer if they just would not configure a file repository in Android Studio at all. Cheers, Stefan ---

Hi Stefan, all-right it looks like Google has to do some work here. Thank you again for your time. Regarding the other (for-me-unimportant ;)) issue: I’m using the gradle-wrapper with sources, and this is all that AStudio is able to resolve in the package: ![](https://global.discourse-cdn.com/gradle/original/2X/5/5d9985ae7d0c1482b589b912a75a25072cd612a9.png) ---

The difference seems to be in signing. Android ships an additional ```gradle > META-INF/GOOGLE_O.RSA > META-INF/GOOGLE_O.SF ``` ---

Stefan, I now use Android Studio 3, the problem has shifted slightly. Can you look at my problem here: > [@Gradle re-execute tasks due to alleged JAR dependency change](https://discuss.gradle.org/t/gradle-re-execute-tasks-due-to-alleged-jar-dependency-change/23115/17): > > I have a problem like this too with android studio. Now I realized the difference in classpath between AndroidStudio3 and console invocation of a task: Android Studio takes some jars from “.gradle/caches/jars-3/” where as console takes everything from “.gradle/caches/modules-2”, Console: :file:/Users/fabian/.gradle/caches/modules-2/files-2.1/com.android.tools.build/gradle/3.0.1/cfa107d4db0c11c11f445a11e768adf61c72ce06/gradle-3.0.1.jar :file:/Users/fabian/.gradle/caches/modules-2/files-2.1/or… ---

This should be fixed in Android Gradle plugin 3.1. Can you confirm? [Previous page](https://discuss.gradle.org/t/task-app-compiledebugaidl-class-path-has-changed/24123.md?page=1)
