[SOLVED] eclipse deleted svn:ignore for folder tmp, still can't import folder

i had previously added a custom svn:ignore entry for "tmp", but today i wanted to undo that so i deleted the entire svn:ignore entry for my project:

then just right-clicked on the svn:ignore property at the bottom right there and chose "delete property".

but i was still unable to import a folder called "tmp" from svn.

eventually i found out that there was some kind of exclude entry for "tmp" as well in the project properties:
right click on project in eclipse > properties > resource > resource filters > delete the exclude entry for "tmp"
