That's right, this artifact is not packaged in Debian. One possibility 
is to package it if it is really needed. However, I think you can skip 
it for your build, the classes of org.kohsuke:github-api do not seem to 
be used anywhere in the software you are interested in. You can simply 
get rid of this dependency by adding the line
org.kohsuke github-api * * * *
to the file debian/maven.ignoreRules (create it, if needed).

Make sure you read
	https://wiki.debian.org/Java/MavenDebianHelper
and the examples at
	https://wiki.debian.org/Java/Packaging/Maven
Also you can look at the sources of other Debian packages using Maven, 
e.g. junit4, biojava6-live, libdistlib-java, ... to see more examples.

Possibly you will meet other unpackaged artifacts in the dependencies of 
Zettelkasten, in which case it is good to look at how their classes are 
used. If not at all, ignoring the artifact as done above is safe.
