我正在尝试将 Cobertura 报告生成集成到我的 azure 管道中。为此，我在 .Net 核心测试项目中添加了 coverlet.collector 3.0.3。下面是我用于测试运行的 yaml 命令
- task: DotNetCoreCLI@2
displayName: Test
inputs:
command: test
projects: '**/*Test/*.csproj'
arguments: '--collect:"XPlat Code Coverage" --settings CodeCoverage.runsettings --logger trx'
publishTestResults: false
我使用 Reportgenerator 任务来合并和发布覆盖率报告。这一切都在我的代码的一个分支中运行良好（一个旧分支，我不久前开始在该分支上设置管道）。但是当我试图指向管道中的最新分支时，我收到如下错误
Data collector 'Code Coverage' message: Data collector caught an exception of type 'Microsoft.VisualStudio.Coverage.VanguardException': 'Running event not received from CodeCoverage.exe. Check eventlogs for failure reason
我检查了两个分支 Microsoft.Net.Test.SDK、coverlet.collector 中的几乎所有内容，它们的版本相同。我不确定 2 个分支之间有什么区别，以及我应该在 2 个代码分支之间寻找什么区别，这可能会导致这样的问题。
下面添加了成功和失败的完整日志。
成功（使用旧分支时）

我也遇到了这个问题线程：https ://github.com/microsoft/azure-pipelines-agent/issues/2839用户怀疑这是代理升级问题，但对我来说似乎并非如此，因为我能够为一个代码分支成功运行它。
