Migration of Plugin to new project - Package build fails


This has been breaking my head for a few days here - I’ve searched so many posts, that I am now doubling back - so I would really appreciate any direction and guidance here.

I will describe what I have done, and what I am try to do.

I created a new UE5.0.1 blank project
I create a new code plugin, to which I edited in Rider
I completed my coding and all is well - builds as expected

I create a new UE5.0.1 (Blueprint) project
I moved my plugin source to the Engine, so I could consume in my new project
I consumed my plugin - I created a specific blueprint to interact with it
I can run the project and it works as I expect

I then attempt to package my project and I get the following error log:

This error has numerous so called fixed in the forums for earlier versions, but it absolute persists in UE5.0.1

The same error occurs regardless of my binary packaging configuration as well.

So - the project runs correctly in debug modes, in editor, in separate window etc, but will not package.

Thanks for anyone with any help with this.

Looks like a Rider issue:


hi - thanks for that - yes i had also saw that and followed up with jetbrains who have said that the issue is not down to rider…

so back and forth we go.

at the end of the day - if i “Migrate” a resource from one UE5 project to another ("the another here not even being a C++ project, so no Rider at all…) - it should be able to compile and more importantly, package the solution.

This is a show stopper at the moment for us.

Just spotted this error when creating a new UE5/3r Person/C++ project

This shows immediately on adding the project name and clicking create
