Building problems. Duplicate entries in BuildConfig.class

[k3t0]

Dear Sandro,

thank you for putting this together. Unfortunately the build process fails for me for both release v1.1.1 and v1.1.0. I'm building with Studio 2.2.3 and JRE 1.8.0_76-release-b03-amd64 and try to run on

• Android 5.1 API 22 or on
• Android 7.1 API 25.
  However, the *.apk files you released do work for me. So the problem should be on my side. Still I would appreciate and hope to get some help on it.

If I clean and rebuild the app, the building works, but when I try to run the app I get:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/local/android-studio/jre/bin/java'' finished with non-zero exit value 2

If I use the option:

   multiDexEnabled true

I get:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/sandro/openalpr/BuildConfig.class

Thank you for any help on this,
k3t0

Hi @k3t0

Can you try to use in your project the buildToolsVersion "23.0.1"?

Dear Sandro,

thank you for your reply.

I'm trying to compile and run an unmodified version of your code. So, I was using buildToolsVersion "23.0.1". I'm now trying to run on a Marshmallow system, but I get the same error.

If I simply build the project, all is well and it logs build successful. Once I try to run/build the apk, however, it exits with the error message shown above.

I understand it's not your job helping me solve my setup issues. Still I'd appreciate any help/idea.
Kind regards,
k3t0

@k3t0 you need to disable instant run. Can you please try it and give feedback?

I had a similar issue. My project had a library module and I had the same package name for both app and library. This was creating the conflict. After I change the library name in the AndroidManifest, it compiled.
