Another difference: I don't get the same auto-complete behavior you did when you typed "main". Did you perhaps hit a shortcut key at that point?

The .java file is apparently not part of the project, however, because I don't have the option to compile it when I right-click on it within the project pane. You can also see that the build says there are no source files to compile. Attempting to run this app gives me the same pop-up error that I get with Ant, with a list of alternative main classes containing just "<no main classes found>". -----Original Message----- From: Geertjan Wielenga <geert...@apache.org> Sent: Saturday, September 21, 2019 6:07 AM To: Walter Oney <walter.o...@oneylaw.com> Cc: Carl Mosca <carljmo...@gmail.com>; Neil C Smith <neilcsm...@apache.org>; NetBeans Mailing List <users@netbeans.apache.org> Subject: Re: FW: screenshot https://youtu.be/HcmcOMZQ0TM Created that especially for you and hope it helps you.

Are you using ‘Java with Maven’ or ‘Java with Ant’? I must be missing something major. The screen shot plainly shows that I'm using Apache NetBeans 11.1 with Ant. Normally, I would think that I've done something wrong, because I learned sometime around 1965 that computers and well-vetted tools rarely make mistakes. Since this isn't my first rodeo, I tend to think that something about the automatic class creation logic is mismatched with the build environment -- probably because I installed the wrong version of something through ignorance. Hopefully, you'll accept a friendly suggestion about how to provide tech support and/or volunteer help: it never hurts to assume that you're dealing with an accurate report of a problem from someone who is missing a crucial piece of information that experienced users possess. In my salad days, I used to send academic users out of the assistance office to lookup something in one of the dozens of IBM manuals that were conveniently mounted in a rack next to the keypunches. I eventually learned that what was transparent to me as a systems programmer was completely opaque to real users. -- Walter C.
