maven-debian-helper: dependency org.kohsuke github-api not found

[Tobias Hilbricht <hilbricht@linopus.de>]

Dear readers,

as my first packaging project I try to package the Zettelkasten Zkn3
app https://github.com/Zettelkasten-Team/Zettelkasten/tree/main
and can build it successfully with maven on Debian bookworm. However,
trying to package it in a deb with mh_helper, I get this message:

In pom.xml: This dependency cannot be found in the Debian Maven
repository. Ignore this dependency?  org.kohsuke:github-api:jar:1.117
[y/N] > 
> dpkg --search /usr/share/maven-repo/org/kohsuke/github-api/*/*

Found perl
Found perl
Found perl

[error] Package perl does not contain Maven dependency
org.kohsuke:github-api:jar:1.117 but there seem to be a match
If the package contains already Maven artifacts but the names don't
match, try to enter a substitution rule
of the form s/groupId/newGroupId/ s/artifactId/newArtifactId/ jar
s/version/newVersion/ here:

Using the suggestions here https://wiki.debian.org/Java/Packaging/FAQ
I do not find a corresponding debian package, but on maven it exists:
https://mvnrepository.com/artifact/org.kohsuke/github-api

How can I satisfy the dependency in a Debian way? Thanks for helpful
pointers

Tobias
