Trying to follow the instructions to package my HelloWorld in a jar.
Where is the Build jar artifacts in the new Community Editions?
You can find it here (under the hamburger menu ≣
):
You can enable Settings | Appearance & Behavior | Appearance | Show main menu in a separate toolbar option to have the main menu always displayed.
Another option is to use Help | Find Action and type Build Artifacts
.
See also this answer for the sample project with the configured artifacts.
