While running the VSO build task (from c5fd92a) on an agent without Git installed I get the following exception:

System.IO.FileNotFoundException: The executable file 'git' could not be found.

It seems like GitVersion still needs the Git command line tool installed on the agent, contrary to the statement of @JakeGinnivan in #562 (comment)). Corresponding code is here: https://github.com/GitTools/GitVersion/blob/master/src/GitVersionCore/LibGitExtensions.cs#L192.

Should we handle this a prerequisite of the build agent and document accordingly, or do you see a possibility to replace all calls to the Git command line tool with LibGit?

Full log is here (note that I used the version from #588 to have the path quoted):

@pascalberger, strange, I pulled from Master and deployed the Custom VSO Task and it worked for me, I saw a separate directory with the external components in it.

@johnkattenhorn Do you have Git command line tools installed on your build agent?

Not that I know of, I didn't add it deliberately. @SimonCropp - Yep they were missing when I checked last night so I built myself from Master.
