SlowCheetah 'File not found' issue when publishing to the file system using msbuild

[trousyt]

I'm using SlowCheetah 4.0.50 and msbuild 17.5.1 on a project using PackageReference.

I'm using msbuild from the command line and publishing to the file system and it seems as though the target ScApplyWebTransforms runs before the files have been copied to obj{Config}\Publish\PublishTmp. Then when the ScApplyWebTransforms target runs, it's unable to find the files to transform in PublishTmp and errors with a FileNotFoundException.

Task "SlowCheetah.TransformTask" (TaskId:47)
  Task Parameter:Source=obj\Release\Package\PackageTmp\log4net.config (TaskId:47)
  Task Parameter:Destination=obj\Release\Package\PackageTmp\log4net.config (TaskId:47)
  Task Parameter:Transform=log4net.Production (Local Publish).config (TaskId:47)

The target depends on PipelinePreDeployCopyAllFilesToOneFolder which looks like it should run before, not after ScApplyWebTransforms to give it a chance to copy the files.

Target "ScApplyWebTransforms: (TargetId:89)" in file "C:\Users\trparkin\.nuget\packages\microsoft.visualstudio.slowcheetah\4.0.50\build\Microsoft.VisualStudio.SlowCheetah.Web.targets" from project "C:\Project s\TFS-Git\HNVOD\src\VODTime\VODTime.csproj" (target "PipelinePreDeployCopyAllFilesToOneFolder" depends on it):

If I modify the Microsoft.VisualStudio.SlowCheetah.Web.targets file and comment out 'ScApplyWebTransforms;' in the PipelinePreDeployCopyAllFilesToOneFolderDependsOn property everything works:

<!-- Required for File System -->
<PipelinePreDeployCopyAllFilesToOneFolderDependsOn>
  $(PipelinePreDeployCopyAllFilesToOneFolderDependsOn);
  <!--ScApplyWebTransforms;-->
</PipelinePreDeployCopyAllFilesToOneFolderDependsOn>

For anyone experiencing the same issue, I started importing the following targets file to fix it.

<?xml version="1.0" encoding="utf-8" ?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Target Name="FixSlowCheetahFileSystemPublish" BeforeTargets="BeforeResolveReferences">
    <PropertyGroup>
      <PipelinePreDeployCopyAllFilesToOneFolderDependsOn>
        $([MSBuild]::Unescape($(PipelinePreDeployCopyAllFilesToOneFolderDependsOn.Replace('ScApplyWebTransforms', ''))))
      </PipelinePreDeployCopyAllFilesToOneFolderDependsOn>
    </PropertyGroup>
  </Target>
</Project>
