Version is empty during Container Publish

[Genmutant]

I'm trying to use MinVer to set the Version Tags of Container images build according to Publish as a Container.

During the build, MinVer sets the Version variable correctly, but when it is used to tag the container, it is empty.

Here is the project file with the log output:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

    <PropertyGroup>
	    <ContainerImageTags>latest;x$(Version)y</ContainerImageTags>
	    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
	    <MinVerVerbosity>detailed</MinVerVerbosity>
    </PropertyGroup>


	<Target Name="VersionMessageBefore" BeforeTargets="PublishContainer">
		<Message Text="=== Version is: $(Version)" Importance="high" />
	</Target>
	<Target Name="VersionMessageAfter" AfterTargets="PublishContainer">
		<Message Text="=== Version is: $(Version)" Importance="high" />
	</Target>

	<ItemGroup>
    <PackageReference Include="Microsoft.NET.Build.Containers" Version="8.0.100" />
    <PackageReference Include="MinVer" Version="4.3.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

</Project>

with calling dotnet publish --os linux --arch x64 /t:PublishContainer -c Release I get:

> dotnet publish --os linux --arch x64 /t:PublishContainer -c Release

  === Version is: 2.1.3
  Building image 'minverversiontest' with tags 'latest,xy' on top of base image 'mcr.microsoft.com/dotnet/runtime:8.0'.
  Pushed image 'minverversiontest:latest, xy' to local registry via 'podman'.
  === Version is: 2.1.3

I expect to get a Tag 'x2.1.3y', but instead I get 'xy'. I added the 'x' and 'y', as with just $(Version) the tag is completely ignored.

It also doesn't work when just setting a singular ContainerImageTag.

I think it worked in the past, but I couldn't get it to work by downgrading to dotnet7. I also tried MinVer 5.0.0-beta.1 which didn't make a difference.

You need to do something like this.

E.g.

<Target Name="MyTarget" AfterTargets="MinVer">
  <PropertyGroup>
    <ContainerImageTags>latest;x$(Version)y</ContainerImageTags>
  </PropertyGroup>
</Target>

Building image 'minvertest' with tags 'latest,x0.0.0-alpha.0y' on top of base image 'mcr.microsoft.com/dotnet/runtime:8.0'.

Well that was much easier than expected. Thanks for the fast help!
