Building rubygem-asciidoctor-pdf

I am trying to build my newly created project in OBS.

Inspiration taken from

I am planning on building it on Leap 15.2, and SLES 15 SP2, since the orignal project does not.
Also because I want that package in the SLES 15 SP2 PackageHub.

The rubygems I could find in the OBS used an gem2rpm.yml to generate the RPM spec file

This file was generated with a gem2rpm.yml and not just plain gem2rpm.

All sections marked as MANUAL, license headers, summaries and descriptions

can be maintained in that file. Please consult this file before editing any

of those fields

However I could not find any information how they did that.

I tried to generate a simple RPM spec using gem2rpm. However it required some manual editing on the end result.
> gem2rpm --template default asciidoctor-pdf-1.5.3.gem
I had to edit the RPM spec

Change the Source spec

Source1: rubygem-%{rbname}


Source1: rubygem-%{rbname}.spec






Requires: ruby ""]


Requires: ruby >= 2.5

Change the




Remove 98 of the 99 duplicated lines under %files


Remove the doc under %files that did not exist

%doc %{gemdir}/doc/asciidoctor-pdf-1.5.3

What I then got, which builds fine

# Generated from asciidoctor-pdf-1.5.3.gem by gem2rpm -*- rpm-spec -*-

How do I create the RPM spec with the gem2rpm.yml?
I want the build process to be a similar as the other rubygems that builds on OBS.

I tried to build the existing project, but it fails to build on Leap 15.2
I can create the source RPM, but building it complains about many missing files
Installed (but unpackaged) file(s) found:

Not sure what I am doing wrong locally.

My own created spec file I can build locally on Leap 15.2
Trying to build it on openSUSE:Factory, fails.

If I commit the spec file from home pevik instead, then it builds on OBS, but it will not build locally.

According to the OBS recommondation, the repository should be a closed transitive.
Meaning it should contain all the necessary RPMs needed?

The rubygem asciidoctor-pdf have the following Runtime and Development requirements.
Does it mean that I have to build each and every one of these myself in my OBS namespace?
