When running Build.bat for the first time error 'No VersionNumber.xml file found' is thrown

After installing OneBuild via NuGet and running Build.bat from the solution root the following error is thrown

Ok, this is a bug in the OneBuild.build.ps1 Read-MajorMinorVersionNumber task. A work around is to manually create a VersionNumber.xml next to the Build.bat OneBuild.build.ps1 in the solution root. An example VersionNumber.xml can be found here https://github.com/lholman/OneBuild/blob/master/VersionNumber.xml
