[D365] Azure Dev Ops build with git as source control

In a previous article I shared the transition from TFVC to GIT as source control provider with Dynamics 365 for Operations (D356fO).

Microsoft does not support Azure Dev Ops (VSTS) automated builds for git repositories by default. When deploying a build environment from LCS, it creates a template build definition with all necessarry steps in the connected VSTS Project - but only for TFVC repositories!

One of the build steps is the one for MSBuild to build the models:

This uses the file AXModulesBuild.proj, which our build environment generated for us with the help of the DynamicsSDK PowerShell Scripts.

If we just change the repository to our git repository and run the build, it fails telling us it could not find the Metadata path!

What is the Metadata path anyway?

It is the path ..\AOSService\PackagesLocalDirectory!
In a TFVC repository you'll find a folder called Metadata which you map to you PackagesLocalDirectory folder.

Why does it not exist in my git repository?

Simply, because git maps the whole repository at once and not single folders individually.
So the ..\AOSService\PackagesLocalDirectory path is already our Metadata folder!

How do I get the build to use the correct directory?

Edit your AXModulesBuild.proj .
Remove the trailing \Metadata from the commands for Generating Modules.proj.
The key starts with <Target Name="GenerateProjFiles"

Check it in and run the build!

We had some cases where we also needed to customize the entry under Project.PropertyGroup.MetadataDirectory with a hardcoded string for the respective build environment topology or to set it in the registry on the build maschine with this PowerShell script:

$registryPath = "HKLM:\SOFTWARE\Microsoft\Dynamics\AX\7.0\SDK"
$newKeyName = "MetadataPath"
$newKeyValue = "K:\AosService\PackagesLocalDirectory"

if (!(Test-Path $registryPath)) {
    New-Item -Path $registryPath -Force | Out-Null
    New-ItemProperty -Path $registryPath -Name $newKeyName -Value $newKeyValue -PropertyType "String" -Force | Out-Null
}
else {
    New-ItemProperty -Path $registryPath -Name $newKeyName -Value $newKeyValue -PropertyType "String" -Force | Out-Null
}
