这可能是由于配置错误导致的问题。请检查构建流程任务中的“发布构建制品”步骤，确保正确配置了“Artifact publish location”和“Artifact name”参数。另外，在代码库中查找指定的Artifact是否已经创建。

示例代码：

steps:

• task: DotNetCoreCLI@2 displayName: 'dotnet build' inputs: command: build projects: '**/*.csproj' arguments: '--configuration $(BuildConfiguration)'

• task: DotNetCoreCLI@2 displayName: 'dotnet publish' inputs: command: publish publishWebProjects: true arguments: '--configuration $(BuildConfiguration) --output $(build.artifactStagingDirectory)' zipAfterPublish: true

• task: PublishBuildArtifacts@1 displayName: 'Publish Artifact: drop' inputs: PathtoPublish: '$(build.artifactStagingDirectory)' ArtifactName: 'drop' publishLocation: 'Container'
