I am making a lib that modifies the AST with an annotation handler for parameter injection (src: http://github.com/PhoenixOrigin/DependencyInjector). Right now, all users are required to include

compileJava {
    options.fork = true
    options.forkOptions.with {
        jvmArgs = [
                '--add-exports=jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED',
                '--add-exports=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED',
                '--add-exports=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED'
        ]
    }
}

in their gradle files. To bypass that, I tried to shade in the required modules with

shadowJar {
    relocate 'com.sun.tools.javac','net.phoenix.javac'
}

But this throws an error here about typecasting between com.sun JavacProcessingEnvironment and the net.phoenix shaded one.

Does anyone know a better way to do it / how to use shadowJar properly to allow for typecasting between com.sun and my shaded classes?
