How can i export a .jar file in Eclipse with sources

I have problem with exporting my work in ecli开发者_如何学Gopse. When i export it does not export with everything that is in src folder. In my program I am reading things from src folder but when i export the program it won't export with the files. I am trying to export it as a runnable jar.

Could you provide some more input? Are you trying to export the jar as a Runnable Jar then it doesn't export by default. Otherwise on the first step when trying to export you can select the files you wish to export.
