Specifying files for restore post action does not work

[Mrxx99]

Product

dotnet CLI (dotnet new)

Describe The Bug

When adding a nuget restore post action, the files argument as described here is ignored and nuget packages are restored for all projects instead.
It does not work whether the files are specified by path (I am not using any source:source or source:target modifiers) or by index.
And the project files are correctly specified as primary outputs.

To Reproduce

Steps:

1. Create a dotnet new template with multiple dotnet projects
2. Add all project files (csproj/fsproj) to primary outputs array
3. add a nuget restore post action with file args and specify only the first project (either by index 0 or by using the path of the project of the first primary output in an array)
4. install the tempalte
5. use the tempalte to create the templates in the CLI
6. notice restore is performed for all project files specified in the primary outputs.

Hi @Mrxx99 ,

Thank you for the ticket and provided details. We are investigating the bug.

[GangWang01]

For nuget restore post action, as
documented the argument files is either a string that is a semicolon delimited list of paths to files, or an array of paths to files. It doesn't support indexes to the primary outputs like other post action.
Actually each path specified in files is used as glob pattern matching relative path of file in source template that is started with ./ or just a full file name without parent path. The doc doesn’t mention about this. We need to improve the doc.
If there is no file matched with glob pattern specified in the argument files, projects in primary outputs will be restored.

For this issue, though the argument files specified by path was not provided, I reproduced it with:

      "args": {
        "files": "AvaloniaTest/AvaloniaTest.csproj;AvaloniaTest.Desktop/AvaloniaTest.Desktop.csproj"
      }

@Mrxx99 let me know if this is not the case and provide detailed argument files specified by path. Then I can do more investigation.

To fix this issue, the file path glob pattern of argument files can be any of below.

	glob pattern
exact path	./AvaloniaTest/AvaloniaTest.csproj;./AvaloniaTest.Desktop/AvaloniaTest.Desktop.csproj
with wildcard *	*/AvaloniaTest/AvaloniaTest.csproj;*/AvaloniaTest.Desktop/AvaloniaTest.Desktop.csproj
with globstar **	**/AvaloniaTest.csproj;**/AvaloniaTest.Desktop.csproj
file name without parent path	AvaloniaTest.csproj;AvaloniaTest.Desktop.csproj
