While trying to do a binding for New Relic's Android agent, I'm getting an error message when packaging that one of the reference jars is not a valid zip file, but I can successfully open it up with tools like Jarzilla.
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Error: Error executing task BuildApk: /Users/davidhathaway/Projects/dwhathaway/xamarin-bindings/NewRelic/NewRelicDroidSample/obj/Debug/__library_projects__/NewRelic.Binding.Droid/library_project_imports/__reference__class.rewriter.jar is not a valid zip file (NewRelicDroidSample)
Build log is here, which shows that the app did build successfully:
Reproduction can be found at - just clean/rebuild/run the "NewRelicDroidSample" app.

The project contains broken links to your local files:
/svn/monodroid/monodroid/out/lib/xbuild/Xamarin/Android/Xamarin.Android.Bindings.targets: error : Specified reference jar not found: ../../../../../../../Downloads/okhttp-2.5.0.jar
This is the first one I saw, there might be more.
I manually downloaded okhttp-2.5.0.jar from maven central, replaced in the .csproj, set build item as EmbeddedReferenceJar and could build without such a jar problem.
Can *you* or anyone else in your team reproduce the issue? I'll also ask at Android team.
This issue is reproducible by running the Android app itself. Consolidated repro (including OkHttp) can be found here:
Also including a video recording of the problem:
Steps to reproduce:
1. Build the solution. Note that everything builds fine.
2. Set the '' project as your startup project, and run.
3. Receive packaging error on deployment.

Radek figured out that the mentioned jar (class.rewriter.jar) is indeed problematic and it contains META-INF/LICENSE.txt *twice*. While some tools wouldn't complain about that it is indeed invalid zip.
While we could still do some workaround, it is basically invalid zip that should be corrected.
unpacked / repacked the jar with the following command, and it's fine now. Even though the jar showed a duplicate license.txt file when I opened it with Jarzilla, exploding it into a folder did not result in duplicate files. Simply unpacking (jar -xvf class.rewriter.jar) and repacking (jar -cvf class.rewriter2.jar .)
After re-packing, I'm now able to compile, and deploy the app including the bound libraries.
Marking resolved. JAR file was invalid. repacking JAR fixed the issue.
