为什么 TeamCIty 构建失败并显示 "because it is being used by another process"，它是否并行构建？

Question

我的服务器上安装了 TeamCity，我的 .Net Core 项目有时会失败并显示以下消息。如果 TeamCity 使用并行构建，那么我该如何禁用它？或者我怎样才能使这个 TeamCity 构建更稳定？

代码在我的开发机器上编译没有任何问题，代码在 Azure DevOps Build 中编译也没有任何问题（a.k.a。Visual Studio 在线）。

Answer 1

您可以添加 MSBuild 开关 /m:1（或 /maxcpucount:1）它说它应该默认为 1，但我也看到关于线程的评论说添加标志修复了一些并行构建问题，所以它可能已经改变了。

文档在这里 https://docs.microsoft.com/en-us/visualstudio/msbuild/msbuild-command-line-reference?view=vs-2017

Answer 2

我在 命令行参数中使用参数详细程度正常级别修复了此问题： -v n

为什么 TeamCIty 构建失败并显示 "because it is being used by another process"，它是否并行构建？

Why TeamCIty build fails with "because it is being used by another process", does it build parallel?
