    Not fixed! I just encountered this with a brand new project in 2019.3.6f1. Did not upgrade from an older version. Developed in Windows for a day, swapped to iOS, then swapped to Android and this occurs.

    The underlying issue is probably fixed but the error message still occurs. This is apparently due to stale caches in the Library folder. Deleting the Library folder and reimporting the Unity project eventually gets rid of the error messages and allows generating an Android project. Arguably this should be fixed too, or a separate issue opened (if not already) to better handle stale cache files.

    first close your project and go to file library in your project and opened after delete all folder and files after open your project in unity 2019.2.10f and wait them to build i hope to work it with you.

    The way I solved this issue is by -> Deleting all the files inside the Library Folder. Steps: 1. Close the editor 2. Goto project folder and backup of Library files (not needed but it's better to be on safer side) 3. After backup just delete all the files inside Library folder 4. Now open editor again and build :)

    By default Unity creates all the Library files once we open the editor. The problem sometimes happens while upgrading project to higher version of Unity is that some of the files are not properly linked/referenced properly. This does not happen always but I had to face this issue while upgrading from 2018_2.1 to 2019_2.4

    Hope this helps!

    Seems to not be resolved at all, upgraded from 2018.2.21f1 to 2019.2.3f1 and got this. Tried removing all plugins, Also I use the Unity Hub SDK/NDK. Still get 30 "Duplicate plugin" errors with empty strings.

    I solved the issue. It looks like that the folder NDK in 2019.2.0.f1 doen´t contains an important file and it generates that compilation issues. I downloaded the previous version of Unity 2019.1.14f1 and i have copied the folder NDK in that version. Later i have deleted the NDK folder in the 2019.2.0.f1 and pasting the NDK of Unity2019.1.14f1 it works fine. I hope that it helps all you.

    I also upgraded to 2019.2.0f1 and now I get the same error as above: " Found plugins with same names, and . " In the error message there is only an empty string for the plugin name. So I don't know which plugin is causing the error.
