Eclipse CDT Invalid Project Path

Question

I have a C project that is built using a makefile, Eclipse constantly warns about \"Invalid project path: Duplicate path entries\", but I cannot figure out what the hell it

Answer 1

Here I just found another way to re-detect the path automatically:

1. Open "Workspace Settings-> C/C++ -> Build -> Settings -> Discovery"
2. Find "CDT Build-in Compiler Settings [Shard]"
3. Click "Clear Entries" and "Reset" button on the right
4. Rebuild projects and Done

Hope this will help.

Answer 2

No needs to remove .metadata guys, just delete all path located in C/C++ General -> Paths and Symbols -> Symbols and replace them on using click buttom but don't give the path manually

Answer 3

It seems like a bug in CDT.

If you really want to get rid of it, you should try getting rid of the spaces in the project path; this was suggested in a search result for the error. If that doesn't work, you can try to open the .cproject file -it's where all the CDT settings lie- and check for an actual path with duplicate entries.
