I’ve been attempting to build a gradle project, and to also update some mappings, but when it comes for the time for Java to compile, it fails. I’ve looked for a possible solution in a few places, but they were usually related with a wrong version of Java. I have tested this problem with openjdk 16.17 and 18, on my linux OS and my windows dualboot. All times they caused this issue. The exception list it gives for it: ```gradle FAILURE: Build completed with 2 failures. 1: Task failed with an exception. ----------- * What went wrong: Execution failed for task ':compileJava'. > Compilation failed;

Besides that `StackOverflowError` should probably not happen and should be reported at [Issues · gradle/gradle · GitHub](https://github.com/gradle/gradle/issues/) with a way to reproduce it, the `compileJava` failure tells you exactly what to do: > Compilation failed; see the compiler error output for details. So scroll up and look at the compiler errors you are given. If you are using IntelliJ you might easily miss it due to this annoyance: [https://youtrack.jetbrains.com/issue/IDEA-226613/Gradle-build-on-failed-build-IDE-auto-focuses-and-shows-incomplete-error-message-which-makes-it-hard-to-understand-why-build](https://youtrack.jetbrains.com/issue/IDEA-226613/Gradle-build-on-failed-build-IDE-auto-focuses-and-shows-incomplete-error-message-which-makes-it-hard-to-understand-why-build) so you need to select a higher node in the tree to see the errors.
