     * last folder (replaced from the base output folder), it's possible to exclude from the input
     * path the parts in common plus the last folder (i.e. all the parts of the output folder).
     *
     * <p>Example of input path: ...mobile/okbuck/buck-out/bin/app
     * /java_classes_preprocess_in_bin_prodDebug/buck-out/gen/.okbuck/workspace/__app.rxscreenshotdetector-release
     * .aar#aar_prebuilt_jar__/classes.jar
