I'm trying to use jpackage to create an installer for my Java app. I'm on
Windows 10 using OpenJDK 15.0.1. I should be able to build an installer using
jpackage --input C:\MyApp --main-jar MyApp.jar
UPDATE: I originally posted that trouble happened when I use the --app-image option, but it happens with just the basic command.
This runs without error, but the resulting executable MyApp-1.0.exe fails to
complete. When I run it, a window briefly pops up and disappears before I
have time to read it, then nothing further happens. It never gets to the
point of asking, "Do you want to allow this app to make changes?". Then if
I try to delete MyApp-1.0.exe, Windows tells me, "The action can't be
completed because the file is open in installer of MyApp." After I restart
Windows I'm able to delete the installer.
Occasionally I'm able to produce an installer that works, and I gleefully jump to the conclusion that whatever variation I just tried is a fix, only to have it fail the next time I try it. Success or failure seems to be random. In particular I've got one version of an installer that works on my Windows 10 laptop, but hangs on my Windows 10 desktop computer.
I've tried it with the early access version of JDK 16 from jdk.java.net, and the problem persists.
This is a follow-up to two earlier posts: jpackage crashes when creating an installer with the --app-image option and jpackage --type app-image creates infinite recursive directories
