Yet another reason: If your pre-build event references another projects bin path and you see this error when running msbuild, but not Visual Studio, then you have to manually arrange the projects in the *.sln file (with a text editor) so that the project you are targeting in the event is built before the event's project. In other words, msbuild uses the order that projects are listed in the *.sln file whereas VS uses knowledge of project dependencies. I had this happen when a tool that creates a database to be included in a wixproj was listed after the wixproj.

如果脚本确实做了它需要做的事情，而Visual Studio只是因为错误而困扰你，你可以添加:

exit 0

到你剧本的结尾。

检查拼写。我试图调用一个可执行文件，但有名称拼写错误，它给了我退出与代码9009消息。

当我的后构建事件脚本试图运行指定路径中不存在的批处理文件时，我有错误9009。

我的解决方案是创建文件的副本，并在构建任务中添加一个步骤，将我的文件复制到原始文件之上。

至少在Visual Studio Ultimate 2013, Version 12.0.30723.00 Update 3中，不能用换行符分隔if/else语句:

工作原理:

if '$(BuildingInsideVisualStudio)' == 'true' (echo local) else (echo server)

不工作:

if '$(BuildingInsideVisualStudio)' == 'true' (echo local) 
else (echo server)
