Question

我在服务器上安装了TeamCity，并且我的.Net Core项目偶尔会失败，并显示以下消息。如果TeamCity使用并行构建，那么如何禁用它？或者如何使TeamCity的构建更加稳定？

代码可以在我的开发机上编译，没有任何问题，代码也可以在Azure DevOps Build（又称为Visual Studio Online）中进行编译。

Answer 1

您可以添加MSBuild开关/m:1（或/maxcpucount:1）它说它应该默认为1，但是我也看到了线程注释，说添加标志解决了一些并行构建问题，所以也许它已经改变了。

Answer 2

我在命令行参数： -v n

中使用参数详细度正常级别解决了此问题

为什么TeamCIty构建失败并显示“因为它正在被另一个进程使用”，它是否并行构建？
