You try to run a Gradle 7.0.2 build with Java 20, that is not supported, you need to use a compatible Java version: [Compatibility Matrix](https://docs.gradle.org/current/userguide/compatibility.html)

For those who are novice like me, Java 20 was indicated by “major version 64” in the error output.

According to [this chart](https://en.wikipedia.org/wiki/Java_version_history), major version 64 is Java 20.

Then, according to [this chart](https://docs.gradle.org/current/userguide/compatibility.html), Java 20 needs Gradle 8.3 (instead of the 7.0.2) that OP is using.
