title: should I exclude source folder from build path (in Eclipse)
body: <p>I have some java projects that use external files as input. I usually store the files in the package directory under a folder which i name "resources". My question now is: should i exclude these folders from the build path? I though that they have to be included, but my programm still works even if they are excluded. Also the logo of the folder changes when i include/exclude the folder. Please see the attached picture. This isnt a very big issue but i was just curious. Thanks for every input on that. </p>
