Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0

Question

Run the Gradle build with a command line argument --warning-mode=all to see what exactly the deprecated features are.

It will give you a detailed description of found issues with links to the Gradle docs for instructions how to fix your build.

Adding --stacktrace to that, you will also be able to pinpoint where the warning comes from, if it's triggered by outdated code in one of the plugins and not your build script.

Try this one

cd android && ./gradlew clean && ./gradlew :app:bundleRelease

I was getting this error. Turns out it only happened when I completely cleaned the RN caches (quite elaborate process) and then created a release build.

If I cleaned the caches, created a debug build and then a release build, everything worked. Bit worrying but works.

Note: My clean command is...

rm -r android/build ; rm -r android/app/src/release/res ; rm -r android/app/build/intermediates ; watchman watch-del-all ; rm -rf $TMPDIR/react-* ; npm start -- --reset-cache

in my case i updated the build.gradle file and make the classpath to latest version from 3.5.2 to 3.6.3

dependencies {
        classpath("com.android.tools.build:gradle:3.6.3") 
    }

The process below worked in my case- First check Gradle Version:

cd android
./gradlew -v

In my case it was 6.5

Go to https://developer.android.com/studio/releases/gradle-plugin and you'll get the plugin version for your gradle version. For gradle version 6.5, the plugin version is 4.1.0

Then go to app/build.gradle and change classpath 'com.android.tools.build:gradle:<plugin_version>
