Eclipse Folder is transparent/grayed out. What does it mean?

Question

My jni folder in Eclipse looks like this:

It is grayed out and has a diagonal line across it. What does it mean? I can still edit my native C++ code in this folder and see the changes as I test the application.

Answer 1

It means the directory is being filtered from the source locations. It seems you can use this to exclude files that are not source from a source folder, although I've never used it.

I got rid of this irritation in Eclipse Indigo CDT by:

(Project) Properties ->C/C++ General ->Paths and Symbols ->Source Location Tab ->Edit Filter... ->Remove

Answer 2

You probably have something in the folder that is deprecated.
