Maven: JAR will be empty - no content was marked for inclusion

Question

I have a minor problem with maven. When I run the command mvn package I get the following warning:

[WARNING] JAR will be empty - no content was marked for in

Answer 1

I hope you have good reason not to follow the standard directory layout, otherwise consider to rearrange the folders: it will make your life a lot easier (as well as for your co-workers). My guess is that nothing has been compiled. In that case: removing the configuration of the maven-compiler-plugin should be enough.
