Error: Duplicate resources is showing when trying to run ./gradlew assembleRelease

React Native version: 0.63.4

Please note that I have already tried the solutions in but still to no avail:

The error that I am receiving is below:

[raw/assets_fonts_galioextra] android/app/build/generated/res/react/release/raw/assets_fonts_galioextra.json
[raw/assets_fonts_galioextra] android/app/build/generated/res/react/release/raw/assets_fonts_galioextra.ttf
Error: Duplicate resources

Probably too simple of a solution / thought, but here's what I'm thinking:

Is it possible that you've copied the assets_fonts_galioextra.json and assets_fonts_galioextra.ttf files yourself to somewhere in android/app/src/main/res/? Maybe you already copied it once, and then some part of the build script is copying it again.

Also try cleaning everything with: ./gradlew clean and then rebuild.

@danielbbt I have the same problem as you and the solutions didn't work for me either.

Did you found something else ? :)

Just to put it out there and to help anyone who is still looking

[raw/assets_fonts_galioextra] android/app/build/generated/res/react/release/raw/assets_fonts_galioextra.json [raw/assets_fonts_galioextra] android/app/build/generated/res/react/release/raw/assets_fonts_galioextra.ttf Error: Duplicate resources

You have a file assets/fonts/galioextra.json which is shown as "assets_fonts_galioextra.json". Notice the other one has the same name, regardless of the extension.

Renaming one of the file will resolve this issue :)

The problem for my setup was this line in app/build.gradle leftover from older react-native versions:

apply from: "../../node_modules/react-native/react.gradle"

removed it and build works now

Closing as this is on a really old RN version, the issue is missing our template and is not actionable. Some of the workaround provided were also valid so there is nothing left for us to do here.
