In the idea, first go to File | Project Structure | Artifacts , there create a new artifact , jar – & gt; From Modules with Dependencies

then build | Build Artifacts

In a good way you have to have an assembly system that herself does it. The most famous is Maven , GRADLE and ant . In addition to the simple compilation in War / Jar, these systems are able to still many useful pieces, including the directory from intermediate files, correct the files at the time of compilation, run tests and much more.
After that, it is enough to add tasks in Run Configurations , and the IDEa itself will be concerned about calling console commands, it will only remain to run the desired configurations.
