Upgrading version

From 0.59.5 to 0.61.5

Description

Duplicate Resources error while generating release APK

Upgraded react-from 0.59.5 to 0.61.5 version. After upgrade tried to generate release APK for the application but build failed with an exception stating duplicate resources for the assets. Tried a workaround by updating the below code in react.gradle file.

  ```

doLast {

def moveFunc = { resSuffix -> 

    File originalDir = file("$buildDir/generated/res/react/release/${resSuffix}"); 

    if (originalDir.exists()) { 

        File destDir = file("$buildDir/../src/main/res/${resSuffix}"); 

        ant.move(file: originalDir, tofile: destDir); 

    } 

 } 

 moveFunc.curry("drawable-ldpi").call() 

 moveFunc.curry("drawable-mdpi").call() 

 moveFunc.curry("drawable-hdpi").call() 

 moveFunc.curry("drawable-xhdpi").call() 

 moveFunc.curry("drawable-xxhdpi").call() 

 moveFunc.curry("drawable-xxxhdpi").call() 

 moveFunc.curry("raw").call() 

}

 

Now after the above workaround we are able to generate release APK successfully but in the generated APK none of the images are present since they get removed but we need to use those images.


## Reproducible demo

Run ./gradlew assembleRelease to get this error.

FAILURE: Build failed with an exception.

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