Click the second jar dependency, because I have a jar package
Small triangle drop-down, choose your jar package
Click ok
Finish up the first point apply, then point ok! Remember to click apply (because I have clicked on a color so grayed out)
Then go to your buld.gradle look dependencies, the package is not much you add ah ~
Finally, because there are dependencies found in the directory tree of this package, we did not know whether this step to add the extra or added.
