Specifically, the problematic files are:
*Engine/Plugins/Online/Android/OnlineSubsystemGooglePlay/Source/Java/com/epicgames/unreal/GooglePlayGamesWrapper.java
Even though I commented out the following lines in the OnlineSubsystemGooglePlay.Build.cs file, the .java file is still being included
//string PluginPath = Utils.MakePathRelativeTo(ModuleDirectory, Target.RelativeEnginePath);
//AdditionalPropertiesForReceipt.Add(“AndroidPlugin”, Path.Combine(PluginPath, “OnlineSubsystemGooglePlay_UPL.xml”));
