Upgrading an old project gives "Found Plugins with the same name" problem

Hi guys,

I had a project that I was working on Unity 2017. I recently updated to Unity 2019, loaded the project and opted for the default project upgrade, and also updated the Android SDK. Now whenever I try to build, I get the below errors:

Found plugins with same names, and . Delete the one of the duplicate plugins.
UnityEditor.AndroidPluginImporterExtension:CheckFileCollisions(String)
UnityEditorInternal.PluginsHelper:CheckFileCollisions(BuildTarget) (at C:/buildslave/unity/build/Editor/Mono/Plugins/PluginsHelper.cs:25)
UnityEngine.GUIUtility: ProcessEvent(Int32, IntPtr) (at C:/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:179)

Notice in the first line that it doesn’t really say which plugins, something seems to be missing. Does anyone have an idea what might be going on here? Thanks.

did u able to find the solution
