Pivotal .NetCore 3.1 dotnet-runtime Error During Deployment

Question

I want to deploy my project using Pivotal from Bamboo. During the deployment of my .NetCore 3.1 project, I'm getting the error "Unable to install dotnet-runtime: could not find a version of dotnet-runtime to install". The deployment stack is set to cflinuxfs3.

I've tried specifying dotnet runtime version (3.1 and 3.1.5) in .csproj file but it got the same error so I removed it.

I've also created a buildpack.yml file and specified the .netcore sdk version as 3.1.x in there.

I'm sharing the property group from csproj and the manifest.yml file.

If you can provide a demo app that reproduces the problem, I'll take a closer look and see if I can update my answer with any more details. — Daniel Mikusa, Aug 18 '20 at 15:55

Ok, here's what is happening.

The code is looking at the RuntimeFrameworkVersion in your .csproj file.
When that is empty, it's going to look at the TargetFramework and attempt to find a substring match using the regex netcoreapp(.*).
It is expecting that to have a single match, but in your case it does not, so you get that error message: could not find a version of dotnet-runtime to install.

Based on your .csproj file, it seems like what you have should be OK though. I did a quick check and the regex works and returns the version.

You could try setting RuntimeFrameworkVersion which would take a slightly different code path and might work for you.

You are trying to perform a source-based deployment. You could try dotnet publish first followed by a Framework Dependent Deployment which again would force a different code path.

It might be that the buildpack isn't finding your file, but it's hard to say without more info.
