[Solved]-Eclipse - CDT programmatically added include paths does not appear-eclipse

i know this has been 3 months so hopefully it's still relevant.

my code looks almost identical to yours but the include paths are shown in properties->c/c++general->paths&symbols and work. so i went through each line and there is only one big difference i can see:

for constructing a new cincludepathentry, the first argument i pass in is an ifolder, not a string, so i am using a different constructor. i am not sure how the rest of your program is structured, but perhaps you can call iproject.getfolder(string) and work with that instead.
