I've tried building it locally but "mvn clean install" gives error. Is there some link that I can use to download prebuilt plugin?

[ERROR] Tests run: 10, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.034 s <<< FAILURE! - in com.sonar.cxx.sslr.impl.typed.InterceptorTest

UPD nvm, I was able to build it with Java JDK 11 instead of 17. I will try it today.
