No possibility to have jar name per project + annoying JAR generation

When you have multiple projects, it's hard to type jar name for every one, especially when they change after restart or you have even more project that the suggestion list can hold.
Having a way to quickly generate the jar to saved jar name would be a lot faster, also option to always override jar file. After that another window shows that you JAR was generated without warning.

Start by reproducing the JAR generation flow described in the issue with multiple projects and observe how names are suggested, saved, and overridden. Identify the relevant export UI and persistence entry points; done would include per-project saved names, quick generation, optional overwrite behavior, and a completion message without an unnecessary warning.
