cannot find symbol ReactNativeFlipper for release build

[VaiteaBimOne]

Description

I'm on react-native 72.4. While doing ./gradlew :app:assembleRelease :app:bundleRelease I have the error:

> Task :app:compileReleaseJavaWithJavac FAILED
/Users/runner/work/1/s/android/app/src/main/java/com/***/***/MainApplication.java:67: error: cannot find symbol
    ReactNativeFlipper.initializeFlipper(this, getReactNativeHost().getReactInstanceManager());
    ^
  symbol:   variable ReactNativeFlipper
  location: class MainApplication

I have 3 env (debug, internal and release) from buildTypes

buildTypes {
        debug {
            signingConfig signingConfigs.debug
            matchingFallbacks = ['debug', 'release', 'internal']

        }
        internal {
            matchingFallbacks = ['release', 'debug', 'internal']
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
        release {
            // Caution! In production, you need to generate your own keystore file.
            // see https://reactnative.dev/docs/signed-apk-android.
            matchingFallbacks = ['debug', 'release', 'internal']
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }

I added the ReactNativeFlipper.java file in all my env except main .../android/app/src/debug/java/com/***/***/ReactNativeFlipper.java .../android/app/src/internal/java/com/***/***/ReactNativeFlipper.java .../android/app/src/release/java/com/***/***/ReactNativeFlipper.java

Now I can build and generate apks for internal and debug but the issue is with release. The only way to make it work is to have the ReactNativeFlipper.java in main with MainApplication.java but that cause the build to fail for internal and debug for duplicate class of ReactNativeFlipper.

Thanks!

I added the ReactNativeFlipper.java file in all my env except main .../android/app/src/debug/java/com/***/***/ReactNativeFlipper.java .../android/app/src/internal/java/com/***/***/ReactNativeFlipper.java .../android/app/src/release/java/com/***/***/ReactNativeFlipper.java

Your setup is correct. You probably have a typo somewhere that is causing the app/src/release/ to be ignored.

Please provide more context or use the reproducer template linked by the bot to reproduce your issue

@cortinico Hi! My bad! My release folder was in the gitignore and the flipper file was not pushed.
