Unhandled exception when running 'paket config add-credentials' in Jenkins pipeline #2884

I have just discovered that trying to run 'paket config add-credentials' within a Jenkins pipeline fails due to trying to do a Console.ReadLine(). This returns null in the context of a Jenkins build and throws a System.NullReferenceException.

Repro steps

  1. Create a Jenkins pipeline that runs the following command:
paket.exe config add-credentials --username **** --password **** 
  1. Run the pipeline

Expected behavior

The default authentication type of basic is taken and the command adds the authentication details.

Actual behavior

C:\jenkins\ws\7958e3d43a>..paket\paket.exe config add-credentials --username **** --password ****
Paket version 5.120.1
Authentication type (basic|ntlm, default = basic): Performance:

  • Runtime: 857 milliseconds

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

Known workarounds

If you supply --authtype basic the command bypasses the Console.ReadLine() command which is the source of the error.
