Hi all, I noticed that openSUSE does not yet have a cryptomator package, so I wanted to try packaging it. Unfortunately this is some kind of java application with a pom.xml, that seems to be built using maven. The wiki page is very out of date (2010), so I am looking for packages that are built using maven, that I could copy from. Searching for maven of course only spits out the maven packages. Does anyone know a nice package that I could take as reference?

Hi all,

I noticed that openSUSE does not yet have a cryptomator package, so I wanted to try packaging it.

sqlite-jdbc looks quite good: https://build.opensuse.org/package/view_file/Java:packages/sqlite-jdbc/sqlit... You can look for other examples by searching for packages that depend on `xmvn` [1].

Thanks Andreas, there are too many osc commands that I use too infrequently to remember. That is a nice one.

I got started on this, and it a lot of fun. Like packaging go without vendoring... Anyways, I thought I had at least partially understood how this should work, but am stuck at an error when trying to prepare a parent-pom package for e.g. planet57-buildsupport:

...

...

Similar issue in sonatype-buildsupport-public-parent:

...

https://build.opensuse.org/package/live_build_log/home:ojkastl_buildservice:...

Any hints on how to solve this? I already added javapackages-filesystem and java-headless to the BuildRequires, but to no avail.
