我在哈德逊有一个用 maven 构建的项目。它编译 C++ 源代码以创建用于项目其他部分的可执行文件。它使用 Visual Studio 工具，特别是会导致问题的工具。当它试图加载 midl 程序时，它找不到它。如果我登录服务器是我的 Hudson 生活并尝试在该特定项目中运行 mvn clean install 我得到：
D:\Hudson\jobs\{project-name}>mvn clean install

解决此问题的一种方法是加载 Visual Studio 工具：
D:\Hudson\jobs\{project-name}>%VS100COMNTOOLS%\vsvars32.bat
Setting environment for using Microsoft Visual Studio 2010 x86 tools.
之后，我得到了一个干净的构建：
D:\Hudson\jobs\{project-name}>mvn clean install
.
.
.

[INFO] BUILD SUCCESS

但是当 Hudson 启动自动构建时，这不起作用。我试图加载该bat文件（vsvars32.bat）执行：
pushd %VS100COMNTOOLS%
vsvars32.bat
popd
在我开始 maven 进程之前，我知道这是有效的，因为我在控制台输出中看到了这个：
C:\Apps\MicrosoftVisualStudio-10.0\Common7\Tools>vsvars32.bat
Setting environment for using Microsoft Visual Studio 2010 x86 tools.
但是每当它到达实际使用 midl 的地步时，我会在 BUILD FAILURE 之后得到这个输出：
[INFO] o.h.m.e.h.MavenExecutionResultHandler - Build failed with exception(s)
[INFO] o.h.m.e.h.MavenExecutionResultHandler - [1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (build-tlb) on project interop: Command execution failed.

我还在 Hudson 配置面板中设置了环境变量对 {VS100COMNTOOLS,C:\Apps\MicrosoftVisualStudio-10.0\Common7\Tools}。我不知道还能做什么，任何帮助将不胜感激。
