error PRJ0019: A tool returned an error code from "Copying DLL..."
提问by Jeff Bloom
Visual studio is giving the error PRJ0019: A tool returned an error code from "Copying DLL...".The console window includes the output: 'CopyDLL.cmd' is not recognized as an internal or external command.
Visual Studio 给出错误PRJ0019：工具从“正在复制 DLL...”返回错误代码。控制台窗口包括输出：“CopyDLL.cmd”未被识别为内部或外部命令。
Here is some background as to why I don't know about the tool which is copying. Someone left the company a year ago and forgot to check in their latest version of code for a MS Visual Studio 2008 project using C# and C+_. Now we need to fix the program, but can't find the code and I've been assigned with trying to clean the mess up.
这里有一些关于为什么我不知道正在复制的工具的背景。一年前有人离开了这家公司，但忘记为使用 C# 和 C+_ 的 MS Visual Studio 2008 项目签入他们最新版本的代码。现在我们需要修复程序，但找不到代码，我被指派尝试清理混乱。

You should check the Custom Build Step (Project Properties->Configuration Properties->Custom Build Step) for all of the projects and all of the files.
您应该检查所有项目和所有文件的自定义构建步骤（项目属性-> 配置属性-> 自定义构建步骤）。
It may be easier to open the *.vcproj files in a text editor and check the tags under individual files in the project. Look for any tags that have a non-empty CommandLine attribute.
在文本编辑器中打开 *.vcproj 文件并检查项目中各个文件下的标签可能更容易。查找任何具有非空 CommandLine 属性的标签。

Turn up the build output with Tools -> Options -> Projects and Solutions -> Build and Run
使用 Tools -> Options -> Projects and Solutions -> Build and Run 打开构建输出
Set MSBuild project build output verbosity to something higher than the default. I'd step it up one level at a time because the highest level is pathologically verbose.
将 MSBuild 项目构建输出详细程度设置为高于默认值。我会一次升级一个级别，因为最高级别在病态上是冗长的。

Go to Tools->Options->Directories and add this… C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE
转到工具->选项->目录并添加这个... C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE
That should do the trick...
这应该够了吧...

I'd never noticed before, but every time you do a build, there's a line printed to the Output window that says:
我以前从未注意到，但是每次进行构建时，输出窗口中都会打印一行内容：
Build log was saved at "file://...
构建日志保存在“file://...
CTRL-clicking on that link will give a lot more detail about the build that failed.
按住 CTRL 键单击该链接将提供有关失败构建的更多详细信息。
In my case, I found 3 "copy" commands, with the wrong filename, which pointed me to the CommandLine attribute in the vsproj file, as suggested by Andrew Garrison.
就我而言，我发现了 3 个“复制”命令，文件名错误，这将我指向 vsproj 文件中的 CommandLine 属性，正如 Andrew Garrison 所建议的那样。
