Identity scaffolder --listFiles option doesn't work properly if default UI was already overridden

Environment: Ubuntu Linux 16.04.6 LTS, dotnet info:

Steps to reproduce:

dotnet new mvc
dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design
dotnet aspnet-codegenerator identity -fi "Account.Login;Account.AccessDenied"
dotnet aspnet-codegenerator identity -lf

It’s a simplified example; in real-world project it might be needed to scaffold another file after the initial ones are already scaffolded or overridden and one might need to consult a list of files quickly.

Expected behavior:

Scaffolder gives a list of files that it can generate.

Actual behavior:

dot_sent@sergey-pc:~/Projects/test$ dotnet aspnet-codegenerator identity -lf
Building project ...
Finding the generator 'identity'...
Running the generator 'identity'...
The below files exist. Use '--force' to overwrite: Areas/Identity/Data/testIdentityDbContext.cs
Areas/Identity/Pages/Account/AccessDenied.cshtml
Areas/Identity/Pages/Account/AccessDenied.cshtml.cs
Areas/Identity/Pages/Account/Login.cshtml
Areas/Identity/Pages/Account/Login.cshtml.cs
   at Microsoft.VisualStudio.Web.CodeGeneration.ActionInvoker.<BuildCommandLine>b__6_0()
   at Microsoft.Extensions.CommandLineUtils.CommandLineApplication.Execute(String[] args)
   at Microsoft.VisualStudio.Web.CodeGeneration.ActionInvoker.Execute(String[] args)
   at Microsoft.VisualStudio.Web.CodeGeneration.CodeGenCommand.Execute(String[] args)
RunTime 00:00:04.08
dot_sent@sergey-pc:~/Projects/test$ 

If I add the -f parameter, the scaffolder lists files successfully.

Additional information about the project being scaffolded, such as:

Target framework(s):

netcoreapp2.2

Package version of Microsoft.AspNetCore.App or Microsoft.AspNetCore.All (if applicable):

2.2.3 - both

Package version of Microsoft.VisualStudio.Web.CodeGeneration.Design - this may be added to your project by scaffolding:

2.2.3

@dot-sent My friend @scottaddie and I just hit this issue in 2.2, but it looks like it’s fixed in 3.0.

BTW, what a really well-written issue! Kudos!

Closing since the issue is fixed in 3.0
