fix: update plugin gradle script

[farfromrefug]

This updates the plugin gradle script:

• no more android support, use androidx
• use java 1.8 (removes warning in the console
• koltin, androidx versions through project properties

no more android support, use androidx

Would that be considered a BREAKING CHANGE?

[farfromrefug]

Do we still support old versions without androidx?

[rigor789]

I'm not sure - some plugins may still use it?

[farfromrefug]

Seems unlikely. And anyway they can deps on their include.gradle. Honestly we should remove them, plus they end up in the .dat metadata...

[rigor789]

👍 - just don't want to break things by accident in a patch release

[farfromrefug]

@rigor789 i think it should got with android runtime 8.2.0 as we move to gradle 7. But i understand your point

[farfromrefug]

@rigor789 @triniwiz that PR now goes further and makes generated plugins aar like 10 times smaller. The consequence is apps dex files getting also much smaller (mine dont even need multidex anymore)

[triniwiz]

All support packages would be jetpacked (if you wanna call it that) .. this looks good for 8.2

superseded by #5774
