Build failure after version upgrade

Sorry. I haven’t upgraded versions for a while and it seems every time I do I get this error at first. This time I can’t find the answer to it. When I build I get the message:
Compilation of " …" failed.
The plugin “RBInternetEncodings.xojo_plugin:0” shares the same filename on disk as another plugin."

I seem to remember I have to move a certain file to another location but cannot remember beyond that. I would appreciate the answer. Thanks Version 2018 Release 2

I changed the name of the application and the build completed without error.

I get this when I have two projects open at the same time with the same name as you mentioned. I do a lot of testing and put test in the app name so I see it quite often.

Here’s my ticket about the problem: <>
