GitHub Actions build for linux - can install but not run

[abulka]

I tried installing the .deb built by the linux build action on my Ubuntu 18.04. Double clicking on the file
https://github.com/wiverson/maven-jpackage-template/releases/download/Ubuntu-latest/testapp_21.40.052006-1_amd64.deb
installs it ok, but finding it via the Desktop search and then running it did nothing. So I ran it from the terminal:

$ dpkg -L testapp | grep bin
/opt/testapp/bin
/opt/testapp/bin/TestApp

andy@ubuntu-amd:~$ /opt/testapp/bin/TestApp

(TestApp:8329): Gdk-WARNING **: 10:55:57.048: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

Update:

I uninstalled it and installed it again using the command line - only to see a broken repository error being reported?

$ sudo apt install /home/andy/Downloads/testapp_21.40.052006-1_amd64.deb
Reading package lists... Done
...
Setting up testapp (21.40.052006-1) ...
W: Repository is broken: testapp:amd64 (= 21.40.052006-1) has no Size information

Despite the error, the TestApp seems to be installed ok, but with the same GDK error trap error when attempting to run it.

FWIW I don't know much of anything about how deb packaging works. I'm just picking up the package emitted by package. 🤷‍♂️

Glancing at the docs https://docs.oracle.com/en/java/javase/14/docs/specs/man/jpackage.html there are a bunch of flags specific to Linux that I'm not familiar with but look a lot like some of the same unique identifier stuff required by other OSes. Maybe setting some of those flags...?

Yeah I don't know much about deb packaging either 🤗. I did some googling and it might be related to GTK versions. In my testing, this launch bug happens in both 18.04 and 21.10 - both of which seem to come with both gtk2 and gtk3. Check with dpkg -l libgtk2.0-0 libgtk-3-0. This post suggests this bug should have gone away viz. "In JDK 10 and earlier, GTK 2 was the default. But from FX 11, GTK3 is now the default."

Trying flag -Djdk.gtk.version=2

This post suggests -Djdk.gtk.version=2 so I took a guess and added

--java-options '-Djdk.gtk.version=2'

to the file src/packaging/linux-jpackage.txt.

When I installed and ran the TestApp .deb, this time I got the error Gtk-Message: 17:28:41.018: Failed to load module "canberra-gtk-module". Same error message under both Ubuntu 18.04 and 21.10.

Trying flag -Djdk.gtk.version=3

This post suggests the flags java -Djdk.gtk.verbose=true -Djdk.gtk.version=3. So I changed src/packaging/linux-jpackage.txt to contain

--java-options '-Djdk.gtk.verbose=true'
--java-options '-Djdk.gtk.version=3'

Under both Ubuntu 18.04 and 21.10 I got:

$ /opt/testapp/bin/TestApp

That is absolute exemplar Linux yak shaving... >_<
