TeamCity构建失败，如何解决“无法启动MSBuild.exe . 无法在路径“？找到项目文件？

我是TeamCity的新手，试图让它第一次构建 . 我昨天安装了TeamCity Professional 8.1.4（build 30168）并设置了我的第一个TeamCity项目 .

Visual Studio解决方案在GitHub上 . 这是一个非常简单的“Hello World”控制台应用程序 . 它在本地构建和运行 .

当我向GitHub提交更改时，会触发TeamCity中的构建 . 因此，触发器起作用 .

构建配置包含一个步骤 . 这是MSBuild . 构建文件路径为％env.BUILD_NUMBER％ . MSBuild版本是Microsoft .NET Framework 4.5，MSBuild ToolsVersion 4，运行平台x86 . 未指定.NET覆盖工具 . 这应该是一个简单的构建：获取最新并构建它 .

这是消息细节：

Failed to start MSBuild.exe. Failed to find project file at path: C:\TeamCity\buildAgent\work\3de96e708f2408e\2

这是构建日志，时间戳已删除：
