Question 1)
I am trying to build a font package.
I am using a _service file to download the source code.
https://build.opensuse.org/package/s...at/cadson-test

The _service file look like this
Which I refer from https://openbuildservice.org/2016/04/08/new_git_in_27/
Code:
<services>
  <service name="obs_scm">
    <param name="url">git://github.com/cadsondemak/cadsondemak.github.io.git</param>
    <param name="scm">git</param>
    <param name="revision">master</param>
    <param name="versionprefix">0.0.20191123+git</param>
  </service>
  <service mode="buildtime" name="tar" />
  <service mode="buildtime" name="recompress">
    <param name="file">*.tar</param>
    <param name="compression">xz</param>
  </service>
  <service mode="buildtime" name="set_version" />
</services>
But I can't get a .tar.xz out of it.

Question 2) How do I delete a file or folder from the source with _service file? Let's say for example, the author have some proprietary fonts mixed with opensource fonts. And I want to only remove proprietary fonts. Thanks.
