“dotnet build”命令找不到 NuGet 包（它们存在）

Question

我正在尝试从 Jenkins 服务器上的命令行构建我的 .NET Core 2.1 应用程序。

它在我的本地机器（Windows 10，Visual Studio 2017 Enterprise）上构建得很好，如果我在 Jenkins 运行的服务器上手动构建它（手动检出 Git 存储库并运行dotnet build ）。 只有当我在 Docker 容器中通过 Jenkins 执行此操作时，它才会失败。

错误： /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] /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]

该包存在于~/.nuget/packages/ 。

我知道我的 Jenkinsfile 目前有点奇怪，但这与我试图让这一切正常工作有关。 似乎dotnet restore工作正常，但dotnet build不知何故找不到这些文件。

我试过指定包目录（通过环境变量，使用dotnet restore --sources和dotnet build --sources 。

我附上了几乎所有我现在能想到的东西，但如果我忘记了什么，请告诉我。 我现在很迷茫。

我的詹金斯档案：

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'

Answer 1

我已通过指定dotnet build应在何处查找 NuGet 包来解决该问题。 它的图像中它不看在正确的位置（虽然我不知道在那里寻找要么...）

我已经使用--packages选项指定了位置。 此选项列在dotnet restore文档中，但未列在dotnet build文档中，即使它在那里也可用（并且您在那里特别需要它）。

您可以按如下方式指定它：

dotnet restore --packages <path>

和

dotnet build --packages <path>

如果需要，它也适用于--no-restore选项。

我的最终 Jenkinsfile 如下所示：

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'
            }
        }
    }
}

我遇到了类似的问题，通过使用dotnet nuget locals all --clear清除全局包和缓存来解决，如解释here 。
