Gradle 8.0 build issue

[alexmirash]

Cause: superclass access check failed: class butterknife.compiler.ButterKnifeProcessor$RScanner (in unnamed module @0x69d73d) cannot access class com.sun.tools.javac.tree.TreeScanner (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.tree to unnamed module @0x69d73d

@jorrrdane I agree as well. It seems to be related to Flamingo upgrade. I just upgraded and run into this problem (Linux).

When I saw errors like this in the past, eventually they were related to the proguard.
But in my case, I am building debug, so proguard should not even be in the picture

I have upgraded a toy project to AGP 8.0 through a few walkarounds below

go to Android Studio Preferences..., then Build, Execution, Deployment / Build Tools / Gradle, then set the Gradle JDK to be of some version 15
