类型 io.invertase.firebase.BuildConfig 被定义多次

Question

I am trying to build a react native application in VSCode. I am getting the following error when I try to build the app. I keep getting the following issue while getting the build complete. I tried to change the firebase version and Gradle updates but did not work.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDexRelease'.

Answer 1

This happens when we try to have multiple packages that overlap when they compile together. This is a very common issue when we are using some older versions of packages.

This specific instance occurs when the user tries to install and use @react-native-firebase/app and react-native-firebase . I used an older version of react-native-firebase for push notifications but as of my knowledge and experience @react-native-firebase/app covers that. So removing react-native-firebase and doing an npm i and then building worked for me.

In general cases, we have to check each package by package and check which one is causing the overlap and either remove it or find some alternatives for the package in the development and build.

Answer 2

In My case I found this as an ultimate error here.

In my package.json file I had, at some point earlier, installed both the @react-native-firebase/app and the react-native-firebase packages.

It seems like the clever auto-importing/linking was bringing both these into the Android project (as it should) which was causing the duplicate class errors. I removed the @react-native-firebase/ packages and now most of my issues have been resolved.

It works for me
