Compilation Issue

[SuperContraptionGuy]

I'm attempting to compile this project using Gradle 7.3.3, but it always fails with this error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
> Failed to calculate the value of task ':app:compileDebugJavaWithJavac' property 'options.generatedSourceOutputDirectory'.
   > Querying the mapped value of map(java.io.File property(org.gradle.api.file.Directory, property(org.gradle.api.file.Directory, fixed(class org.gradle.api.internal.file.DefaultFilePropertyFactory$FixedDirectory, /home/blackdoctor/Development/gentle-glow-onyx-boox/app/build/generated/ap_generated_sources/debug/out))) org.gradle.api.internal.file.DefaultFilePropertyFactory$ToFileTransformer@e2dea31) before task ':app:compileDebugJavaWithJavac' has completed is not supported

Does someone who has successfully built this project have any advice? I'd like to try tinkering with Onyx boox projects, but this compile error occurs with all of them. Surely it's my setup that's the issue, but I don't know how to fix it.
