Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

Hi @renishdeveloper, thanks for submitting this issue!

Unfortunately, this issue is not reproducible for me. I've created new project via create-react-native-app, I've added react-native-screens and tried npx react-native run-android - no issues there, the app is being built correctly.
My first assumptions is the wrong version of Java installed locally - in my case I'm using openjdk 11.0.20 from Zulu.
Also, do you have jvmTarget specified in your gradle files? If so, what is the version you're using in the project?

Cheers!

Hi @tboba i am facing this issue in 2 application when i install react-native-screens

Task :react-native-screens:compileReleaseKotlin FAILED

Task :react-native-safe-area-context:compileReleaseKotlin
'compileReleaseJavaWithJavac' task (current target is 11) and 'compileReleaseKotlin' task (current target is 1.8) jvm target compatibility should be set to the same Java version.

I struck this today after doing something completely unrelated to react-native-screens. I installed react-native-vision-camera and react-native-fs, then started getting this error each time I tried to build even after I removed those libs (and yes, trashed yarn.lock and node_modules/*, reinstalled everything and ran npx jetify each time).

The thing that fixed it for me was commenting out export JAVA_HOME=$HOME/OpenJDK/jdk-20.0.2.jdk/Contents/Home/ in my .zshrc file.

After that, for java --version I get java 11.0.18, and the builds work again.

Its' wierd that this suddenly came up, as I've had that OpenJDK version installed/used for a while and it was building fine as recently as yesterday.

Hi @mrtomhoward ,

  Thanks for your response, i also yesterday downgrade my java version 20 to 11 and working fine for me also.

This is issue with latest java version.

RN uses Java 11 on versions before 73 (or 72, I do not recall exactly), and 17 for later versions. We do not test for compatibility with Java 20.

^ brew uninstall java --ignore-dependencies && brew install java17 fixed this issue for me.
