Today I just want to run packaged jar package, have a problem.
The reason is that my code is so written:
And I jar directory where the package was not such a src folder.
So I just put the bag on the jar has src directory folder can be. Say one more thing, in fact I write is not very good, I do not really should put music, pictures, placed in the src directory, should be placed under a separate directory resources would be better.
In this directory run the jar package successfully.
