Unsupported class file major version 66 error. about cli HOT 5 OPEN

@avcismail I came across this issue when looking at a build issue with an unrelated project. I'm not terribly well-versed in Gradle, but I think the issue is that the latest version of Gradle (8.7) does not support Java 22. When I switched to Java 21 the error went away and I was able to build the project that was problematic for me.

from cli.

confused, bc it says here, that java se 22 does infact support class 66

@cacami6564844, java se 22 supports class 66, but according to this you cannot run gradle 8.7 with java se 22.

from cli.

I have the same issue.

Hope it will help.

hey! @avcismail Please follow these two steps, and let me know if you still encounter your issues.

1. Make sure that you're using proper Java version for your project,
2. Make sure that npx react-native config passes.
