'dotnet build' command not finding NuGet packages (they exist)

Question

I'm trying to build my .NET Core 2.1 application from the command-line on my Jenkins server.

It builds fine on my local machine (Windows 10, Visual Studio 2017 Enterprise), and if I manually build it on the server Jenkins is running on (manually checkout Git repository and running dotnet build). It's only when I'm doing it through Jenkins in a Docker container that it fails.

The error: /usr/share/dotnet/sdk/2.1.403/Sdks/Microsoft.NET.Sdk/targets/Microsoft.PackageDependencyResolution.targets(198,5): error NETSDK1064: Package Microsoft.CodeQuality.Analyzers, version 2.6.2 was not found. It might have been deleted since NuGet restore. Otherwise, NuGet restore might have only partially completed, which might have been due to maximum path length restrictions. [/var/lib/jenkins/jobs/pr-builder/jobs/cgi-api/branches/PR-18/workspace/API/API.csproj]

The package exists in ~/.nuget/packages/.

I'm aware my Jenkinsfile is a bit weird at the moment, but that has to do with me trying to make this all work. It seems dotnet restore is working fine, but dotnet build is somehow not locating these files.

I've tried specifying the package directory (through the environment variable, with dotnet restore --sources and dotnet build --sources.

I attached pretty much anything I could think of at the moment, but if I forgot something please tell. I'm pretty lost at the moment.

My Jenkinsfile:

pipeline {
    agent {
        docker {
            image 'microsoft/dotnet:2.1-sdk'
        }
    }
    environment {
        HOME           = '.'
        NUGET_PACKAGES = './.nuget/packages/'
    }
    stages {
        stage('pre-build') {
            steps {
                // logging tooling versions
                sh 'dotnet --info'
                sh 'find ~/.nuget/packages/microsoft.codequality.analyzers/ -type f'
                sh 'dotnet nuget locals all --list'
                sh 'dotnet restore'
                // sh 'dotnet clean'
            }
        }
        stage('build') {
            steps {
                // sh 'dotnet restore --force --no-cache'
                // sh 'ls ./packages/'
                // sh 'find ./packages/microsoft.codequality.analyzers/ -type f'
                sh 'dotnet build --no-restore'
            }
        }
        stage('test') {
            steps {
                sh 'no test project configured'
                // sh 'dotnet test'
            }
        }
    }
}

I've resolved the issue by specifying where dotnet build should look for the NuGet packages. It that within the image it doesn't look at the right location (although I'm not sure where it is looking either...)

I've specified the location with the --packages option. This option is listed in the dotnet restore documentation, but not in the dotnet build ones, even though it is available there as well (and you need it there, specifically).

You can specify it as follows:

dotnet restore --packages <path>

and

dotnet build --packages <path>

It works with the --no-restore option as well, if you need that.

My final Jenkinsfile looks as follows:

pipeline {
    agent {
        docker {
            image 'microsoft/dotnet:2.1-sdk'
        }
    }
    environment {
        HOME = '.'
    }
    stages {
        stage('pre-build') {
            steps {
                // logging tooling versions
                sh 'dotnet --info'
                sh 'dotnet nuget locals all --list'
                sh 'dotnet clean'
            }
        }
        stage('build') {
            steps {
                sh 'dotnet build --packages ./.nuget/packages'
            }
        }
        stage('test') {
            steps {
                sh 'echo no test project configured'
                // sh 'dotnet test'
            }
        }
    }
}
