Hello , I am quite new to the world of Game engines and Coding. I am an artist and using Blueprint I was trying to get an arch viz project done with just some assets and the 1st Person shooter BP.
As the project was evolving I kept packaging and building( all for windows x64) , checking if all works. After a wile I kept getting this line of code on package. anyone has any Idea where to start? Bare in mind I don’t understand code 2 well but I can follow steps:P

Attached the full log

Same problem in my case:
Program.Main: ERROR: An item with the same key has already been added.

No idea what causes this situation.

Same problem here. Epic…?

Rankal_1 · August 20, 2015, 1:09pm

so I found the problem my end if anyone still cares. There is a target file in the source folder and somehow I managed to duplicate it. i searched for .target in the windows search bar and deleted one of them. Worked. The problem occurred as I was running it from Google drive folder on 2 different PC’s and it must have duplicated it. Don’t use anything like Dropbox or GDrive with projects it breaks them. Tortoise SVN my next choice worked like a charm

anonymous_user_c0687f281 · August 20, 2015, 1:11pm

Thanks, but there is no *.target file in my whole project…

Do you mean this folder here?

anonymous_user_c0687f281 · August 20, 2015, 1:30pm

I don’t use Dropbox or Googledrive and there seems to be no *.target file in my project.

Thank you, this problem appeared when I’ve duplicated a project under 4.11

anonymous_user_e756e0ec · March 15, 2017, 8:27pm

Yes! Fixed it for me; I was pulling my hair out over here lol

thank you for this fix

iBrews · June 12, 2017, 7:26pm

wow, can’t believe that fixed it. thank you! in my case it seems like the problem was that I had changed the name of my project, and there was a .target file that still had the old name of the project. Deleted that and everything was fine!

Thank you, it worked!

I had this problem after duplicating a project in 4.16. The target file was duplicated, but removing it alone did not help.

What did work in the end was deleting the whole Intermediate folder.

This is the post you’re directed to when you’re being punished for not using good Versioning Control…

Thank you!
