我在Hudson上有一个项目,使用maven构建。它编译C++源代码以创建可在项目的其他部分中使用的可执行文件。它使用Visual Studio工具,特别是一个导致麻烦的工具。当它尝试加载midl程序时,找不到它。如果我登录到存放Hudson的服务器并尝试在该特定项目中运行mvn clean install,则会收到以下错误消息:
D:\Hudson\jobs\{project-name}>mvn clean install

解决这个问题的方式是加载Visual Studio工具:
D:\Hudson\jobs\{project-name}>%VS100COMNTOOLS%\vsvars32.bat
Setting environment for using Microsoft Visual Studio 2010 x86 tools.
完成此操作后,我成功生成了一份干净的构建版本:
D:\Hudson\jobs\{project-name}>mvn clean install
.

但是,当Hudson自动启动构建时,这种方法就不再适用了。我尝试通过执行以下步骤来加载那个bat文件(vsvars32.bat):
pushd %VS100COMNTOOLS%
vsvars32.bat
popd
在开始maven进程之前,我知道这个工作是有效的,因为我在控制台输出中看到了这个信息:
C:\Apps\MicrosoftVisualStudio-10.0\Common7\Tools>vsvars32.bat
Setting environment for using Microsoft Visual Studio 2010 x86 tools.
但是每当到达实际使用MIDL的时候,我在BUILD FAILURE之后得到以下输出:
[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}。我不知道还需要做什么,请帮忙检查一下。
