Question 1)
I am trying to build a font package.
I am using a _service file to download the source code.

The _service file look like this
Which I refer from
  <service name="obs_scm">
    <param name="url">git://</param>
    <param name="scm">git</param>
    <param name="revision">master</param>
    <param name="versionprefix">0.0.20191123+git</param>
  <service mode="buildtime" name="tar" />
  <service mode="buildtime" name="recompress">
    <param name="file">*.tar</param>
    <param name="compression">xz</param>
  <service mode="buildtime" name="set_version" />
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.
