dotnet new -i not reporting errors and exclusions not working as expected

Doing some work on this PR at the moment. https://github.com/eShopWorld/template-webapi-fabric/pull/23

On my final test to install the template it just bombs out with no errors:

nuget pack C:\[path]\template-webapi-fabric\src\Eshopworld.WebAPIFabric.Template.nuspec

create new dir, navigate to it and run

dotnet new -i C:\[path]\template-webapi-fabric\src\Eshopworld.WebAPIFabric.Template.1.0.8.nupkg

The previous version does work as expected ie: 1.0.7. This is what is also in the master branch and creating this template on my machine runs just fine.

After you check what has been installed with 1.0.8 you are left with just the standard set of templates as outlined here:

Examples:

Additionally, the exclusions within the https://github.com/eShopWorld/template-webapi-fabric/blob/bc04a29e681554861ccf35d287fc1c1702bbe883/src/.template.config/template.json do not seem to work as expected. I’ve tried a few varieties of options here and played them within the modifiers array as suggested here https://github.com/dotnet/templating/issues/850 but to no avail.

Any help on both issues would be appreciated.

Thanks Dave

Above was implemented and merged to main branch, only list of installed templates is shown to users now, closing.

The issue will be fixed with https://github.com/dotnet/templating/issues/2745, when implementing that epic install-uninstall was majorly reworked.

The error messages and the result of installation will be now shown to user. If installation was not successful, the error and the reason will be shown to user.

Draft example:

> dotnet  new  -i Take.Blip.Client.Templates::0.50.10 --nuget-source https://api.nuget.org/v3/index.json
The following template sources will be installed:
  Take.Blip.Client.Templates, version: 0.50.10

Warning: Take.Blip.Client.Templates::0.50.10 is not found in NuGet feeds https://api.nuget.org/v3/index.json.
'Take.Blip.Client.Templates::0.50.10' could not be installed, the package does not exist.

If installation was successful, the list of installed templates will be shown to user:

dotnet new3 -i Microsoft.Azure.WebJobs.ItemTemplates
The following sources will be installed:
  Microsoft.Azure.WebJobs.ItemTemplates

The template source Microsoft.Azure.WebJobs.ItemTemplates::3.1.1648 was successfully installed.
The following templates were installed:
