I am trying to build a custom IDE, I generated the build.xml using the wizard. It is giving me a strange error, one of my languages is apparently the cause of it. The error message says :
Error: There are two modules visible from the project [MyProject] with the same name "FeatureModel"
The error goes on saying how both modules are from the same model in my MyProject.build.mps file.
I went and checked that file, and upon search, "FeatureModel" returns 7 matches, 6 of which appear in the same node (concept="1E1JtD", role="2G$12L") which I assume is the type of nodes that contain my modules since there's the exact number of those nodes (4 in this case) and they contain the names of my other modules. The other match appeared after I fixed an error with one of my other languages' dependencies by using the "Reload modules from disk" intention, and in the same node is contained the name of another language that is also a dependecy so it is definitely not causing the error.
I also searched for the uuid of my language, which only appeared once.
Now, this language used to be called differently and also used to contain a lot more concepts, and when I first inspected it I found a bunch of folders with the old name containing the old files which I had forgotten to delete. I have deleted those folders since then, to no avail.
I have tried generating a MPS plugin instead, but the same error appeared, and I have made sure that MPS was up to date, which it is. I have no idea what is causing this issue or how to fix it.
Thanks in advance for taking the time to help me with this error.
