Jenkins dotnet lambda deploy-serverless Could not execute because the specified command or file was not found

Question

I am new to CI/CD and trying to deploy a simple serverless function through Jenkins and getting error.

Here are my steps

1. Create a new project using dotnet new serverless.AspNetCoreWebAPI
2. Configured Git source {GitHub} where this project is located.

3. Added following lines in Build Step

   `export PATH=$PATH:/usr/local/share/dotnet:/usr/local/bin

   dotnet lambda deploy-serverless`

After running the above command I get the error

/usr/local/share/dotnet/dotnet lambda deploy-serverless Could not execute because the specified command or file was not found. Possible reasons for this include:
You misspelled a built-in dotnet command.
You intended to execute a .NET Core program, but dotnet-lambda does not exist.
You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.
Build step 'Execute shell' marked build as failure Finished: FAILURE

Needless to say I can successfully run dotnet lambda deploy-serverless if using terminal window.

Any idea what's wrong here?

Answer 1

Install first below command in CMD

dotnet tool install -g Amazon.Lambda.Tools

Then you can find dotnet command in cmd.

Answer 2

Solved the issue finally.

Compared the .csproj files one for successful lambda deployment and one where it was failing. Noticed that following lines were the difference. It worked as soon as I added the below in my project file.

<ItemGroup><DotNetCliToolReference Include="Amazon.Lambda.Tools" Version="2.2.0" /></ItemGroup>

It will be still interesting to know that why dotnet lambda deploy-serverless works from terminal window for the same project without the above line but not from inside jenkins job.
