I checked all posts talking about this error:
Failed for task ': transformClassesWithJarMergingForDebug'
But none of them corresponds exactly to my case, and none of them answered / did not solve my problem ... I was tired of the search (about 12 hours and did not find anything ...)
Explaination
I am using Ionic (latest version) to create an application. My first problem was related to the SenderID problem: I can’t put it in the init function, but when I deleted it, it didn’t work on Android ... And when I said that, it said that it could not be assigned PushOptions , you see trick.
Actual error
The actual error that I have is the following:
Execution failed for task ': transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org / apache / cordova / BuildHelper.class
Here is what I did to be here:
Actions
So, I decided to switch to cordova-plugin-fcm , as I see in different places, that it is easy to configure. Go through it, generate all the necessary files ( google-services.json , etc.), Install and run all the TS that the plugin needs: there are no TS errors.
My problem: when I run ionic cordova run android - or just build, the same thing - I had problems with multiple values:
First mistake
At first I had a problem with the game services, which is unknown, so it will go through version 9.0.0: I decided to use it using cordova-plugin-firebase and cordova-android-play-services-gradle-release .
Second mistake
Secondly, I had this one:
Execution failed for task ': transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org / apache / cordova / PermissionHelper.class
What I decided with:
cordova plugin rm cordova-plugin-compat --force cordova plugin add cordova-plugin-compat@1.2
But now I am stuck in a "Real Error" and could not create my application.
