Crossed folders in eclipse luna

Question

I've just installed Eclipse Luna and in my project explorer there are appearing some folders crossed out, and I don't know how to remove it and even what it means.

Looks like the Engine and Gameplay folders are also being duplicated. What is going on?

Thanks

Answer 1

I had a similar (the same?) issue after creating a new folder in an existing project. Having found this (incredibly slowly-loading) documentation page, I figured out the gray diagonal line in CDT can actually also mean "excluded from build".

This was readily countered by right-clicking on the folder in the project explorer, choosing

Resource Configurations -> Exclude from Build...

and then deselecting all configurations.

Answer 2

What I did was go to:

Project properties ->C/C++ General ->Paths and Symbols

There I added the folder to the include directories and at the Source Location Tab I clicked on:

Edit filter -> Remove

I think it has to do with how you added the folder to the project (through eclipse, as a source folder or externally)
