Does react-native support jdk 17?

Question

So I have been having some problems with launching the initial react-native template project on android. And after consulting someone I was told that jdk 17 is not supported. But I really don't want to downgrade as this could break other things that I already have and work with. To be specific this is the error I get:

> Task :app:processDebugMainManifest FAILED

FAILURE: Build failed with an exception.

I have looked at this already and nothing worked. Gradle: Execution failed for task ':processDebugManifest'

Answer 1

To know if this is a java version-related issue, You need to check your Gradle version.

currently only Gradle version 7.3 support java 17.

You can check gradle compatibility matrix to check.

you can check your version with the command line by typing gradlew.bat -version

If your Gradle is version 7.3 then it has nothing to do with the JDK version.

Answer 2

So I solved this issue by installing JDK 16 on my system and everything is solved and running fine. I don't know if the problem was with Gradle or JDK or react-native but hope it is fixed.

If you have the same issue then you can go to: jdk 16

and download the JDK 16.
