Problem description

The publish task Publish_GitHub_Wiki_Content failes due to missing wiki page.

@gaelcolas, can you create just a dummy first wiki page to create the wiki repository?

The wiki is created, so the issue is not there.
I know Johan has worked on this so it may be fixed on a pre-release of DSCResource.DocGenerator..

All changes are currently released. We had this before, and it is due to something is not right in the repo I think. I don't remember why this happened from the top of my head.

[johlju]

Okay, this is because the file Home.md in WikiSource does not have the version tag in the file.

By having v#.#.# in the markdown file the task will update the Home.md (in WikiOutput) on each release. So then there is always something to commit to the GitHb repository. Normally we have the below in the Home.md.

<sup>*SqlServerDsc v#.#.#*</sup>

So the bug is that it should not try to commit if there is no diff.

@johlju, the build is still failing after changing the content of the home.md.

Do we also have to change the already existing content in the wiki that yet does not have a version tag?

[johlju]

In Home.md in WikiSource you need to have the tag v#.#.# somewhere in the document. Then the DocGenerator task will replace that with the actual release semantic version when it saves the Home.md in output/WikiOutput
