How do I get Gradle to run the java compiler?

I'm running Gradle 7.4.2, and get an error that there was a problem starting the compiler. I cannot find any details or reason. Why isn’t the error message from launching the compiler output to the log? The message recommends using --scan, but I’m doing that.
