`--add-exports` not weaved into args for JavaCompile

[wadoon]

It seems, that --add-exports definitions are currently not used for JavaCompile.

Following configuration does not effect the compilerArgs:

javaModule.hacks {
    exports("javafx.graphics","com.sun.javafx.scene.input",javaModule.name)
    exports("javafx.graphics", "com.sun.javafx.css", javaModule.name)
}

Following snippet is a workaround:

compileJava {
    doFirst{
        def cli = new JigsawCLI("")
        javaModule.hacks.applyHacks(cli)
        def args = cli.generateArgs()
        args.remove(0)
        args.remove(0)
        options.compilerArgs.addAll(args)
    }
}

Plugin version: 0.3.1, Gradle: 4.7, Java 10.
