Ionic AztectDetectorResult.class error

Ionic Framework ionic-v3
1

Hey everyone,

I have been keeping on getting this error in ionic all of a sudden

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/zxing/aztec/AztecDetectorResult.class

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

[ERROR] An error occurred while running cordova emulate android (exit code 1).

This error goes away after I uninstall phonegap-plugin-barcodescanner. However, after reinstalling phonegap-plugin-barcodescanner, the error arises again. (Note: I have been using barcode scanner for a couple of months now and it never caused any issues until now). Any help would be greatly appreciated! :slight_smile:

Hi, I have the same problem too. :tired_face:

I am trying to change the graddle file but I did not succeed.

But I still have not given up if I can evolve with something I’ll be happy to share!

I was able to get my issue figured out.

I ran npm install gradle

Then I removed the android platform and readded it. Then everything worked fine.

Hopefully this helps you! :slight_smile:

I tried the same procedure here but I did not succeed.

I’ll share my log here.

Can you provide a list of your plugins being installed (cordova plugin ls)?
