TeamCity Nuget Installer step fails saying Failed to find NuGet executable

Question

I have created a TeamCity buils step using Nuget Installer, but when I run the steps I get the error :

But I have downloaded the Nuget.exe below are the screenshots:

Not sure what am I missing? Any help is much appreciated! Thank you.

Answer 1

So after breaking my head over this, I managed to find the solution.

At the time of downloading nuget.exe in Teamcity - Administrator>Integration>Tools>Nuget.exe>Installed Version>3.4.3

if teamcity agent is already running & you try to run a new build, the agent can never detect new installations(in this case nuget.exe) and so it fails.

Solution - restart the agent ->in command prompt C:\TeamCity\buildAgent\bin>agent.bat stop force and then C:\TeamCity\buildAgent\bin>agent.bat start.

Now go to Administration>>Project_name>Build Steps>Parameters

• Add a new Parameter
• Configuration Parameters
• Name : teamcity.tool.NuGet.CommandLine.DEFAULT
• Value: Browse the small box and select- %teamcity.tool.NuGet.CommandLine.3.4.3%
• Save

Run the Build

The Nuget Installer Step runs fine and restores the packages.
