I did a plugin for UE4.26 that works ok. Now I am working on UE4.27 and I try to use the same plugin but it fails when I try to launch de game on the device.
It claims I have a duplicated class. Is there a way to disable it?
Why U4.26 goes ok and 4.27 fails with that error?
Any help?

Note: everything builds ok when I package the plugin and then I compile in Rider:
In my case I had a folder inside a .jar that UE4.27 didnt liked (found as duplicated classes).
I fixed it just extracting the .jar contents (its a zip), removing that folder and compressing again as .jar. I could not find the other ‘duplicated’ files in my project but that fixed my problem.
It’s strange UE4.26 don’t give that error and compiles ok.
just in case this androidx folder with those 4 files was the source of the problems:
Yesterday I thought I had solved it but no What I did solved the LAUNCH
issue where it failed stating a duplicated class was there.
Now I want to make a distribution APK and I get this error
I dont have this issues on 4.26,this happens on 4.27 only.
