TeamCity和Team Foundation Server 2012的构建步骤失败

已更新，包含图像。TeamCity和Team Foundation Server 2012的构建步骤失败

在TeamCity中设置项目时，无法使构建步骤起作用。我每次都会收到相同的错误。

未能启动MSBuild.exe。无法在路径中找到项目文件：C：\ TeamCity \ buildAgent \ work \ 42c94c0380966ffa \ Main \ Solution.sln

我能够连接到TFS。在哪里我把根作为如下。

$/Projectname/

测试连接返回ok。

创建构建步骤时，我使用MSBuild并将构建文件路径设置为解决方案存在于tfs结构中的位置。举个例子。

构建文件路径：主\ MySolution.sln

因为在TFS这就是解决的办法是。 $ /项目名/主/ MySolution.sln。当我运行构建步骤时，出现上述错误。我究竟做错了什么？ 42c94c0380966ffa文件夹在光盘上创建，但它是空的。
