Cause: superclass access check failed: class butterknife.compiler.ButterKnifeProcessor$RScanner (in unnamed module @0x548587cc) 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 @0x548587cc

[collosia]

This might be because butterknife tool is now deprecated.
