Hi Hiran,
My apologies for not replying to your previous email. In that particular
case the problem seems to be in missing "--name" cli option on the
second jpackage command line ($JAVA_HOME/bin/jpackage --app-image
build/app-image --verbose --dest build) that is supposed to build .deb
package from the app image.
Could you please confirm this is the case so I can file more specific
description in a CR tracking this issue.
Do you have a stack trace for the second NPE? It would help to
understand what went wrong.
Issue with the Github Runner looks similar to this one [1]

Hi there.
I have another case where running jpackage emits
Bundler DEB Bundle failed because of java.lang.NullPointerException:
Cannot invoke "java.lang.CharSequence.length()" because "this.text" is
null
I have never experienced NullPointerExceptions in other JDK tools.
Seems to me JPackage is a new kid on the block. In this case, JPackage
is invoked to finish from an existing appimage to the final package.
the failure is caused because some important files are missing in
appimage.
The previous run is even more puzzling for me. It is supposed to create
the appimage directory. And while it emits no error message, on my
development machine it runs reliably while on the Github Runner it just
does not create all files - no error message, no exit code - nothing.
Any idea what I could be looking at?

Hello Alex,
I tried running the same command with the jdk19 you pointed at. As a
first, I get this output:
$JAVA_HOME/bin/jpackage --version
19-ea
With that, I invoked the command as before, and i fairly got the same
output. So the behaviour in the latest version has not changed.
Two things I'd like to point out:
- there is no JPackage version in the output itself so both you and
me
have to trust the correct one was called
- I found out the mistake: I should have used
--app-image build/app-image/SettlersRemake
but JPackage gave a warning in the beginning and processed all the
rest

Hi Hiran,
Looks like jpackage fails because of missing package name on the
command
line.
I agree that the error message is not helpful. Can you try one of
jdk19
EA builds [1] to see if the problem is reproducible?

Hello there.
While I am trying to package my project using jpackage 16.0.1 on
Ubuntu
20 LTS I have difficulty in assembling the correct commands.
The documentation covers a lot but not everything. For example,
it
is
not clear to me when I have to provide an option - especially
since
I
meanwhile take a two step approach of building the appimage, then
tweaking something (that could have done by JPackage directly)
and
finally building the DEB package.
While I believe the documentation is good enough, the error
messages
presented by JPackage are not. Here is one example. Hopefully you
agree
that the NullPointerException does not at all tell me what is
wrong
and
what I could improve on.
My feeling is that JPackage should do some better error handling
and
come up with improved messages.
