I would appreciate this too. I once tried to get a swift library working with this apporach, but failed somehow.
It may be the wrong thread, but hope the community will write such a guide to help others. At the moment, i do try to convert code from obj-C to java, as soon as it’s possible. But this is struggle.
Please review this pull request that fixed builds with gradle v6 for us (tested 6.0 and 6.3).
Thanks! I’ve publish the 1.5.1 which contains your fix.
