exec-maven-plugin表示无法运行指定的程序，即使它位于PATH上 [英] exec-maven-plugin says cannot run specified program, even though it is on the PATH
问题描述
编辑20140716 ：
tl; dr = exec-maven-plugin 不识别 .cmd 文件，但只有 .bat 文件，作为可执行脚本。重命名 grunt.cmd - > grunt.bat ， bower.cmd - > bower.bat 等作为解决方法。
tl;dr = exec-maven-plugin does not recognise .cmd files, but only .bat files, as executable scripts. Rename grunt.cmd --> grunt.bat, bower.cmd --> bower.bat, etc. as a workaround.
完成我的系统上的npm install -g grunt-cli ， grunt 肯定是在 PATH
当我运行 maven install 但是，这似乎没有注册。
When I run maven install however, this doesn't seem to register.
[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec
(build-spa-bower) on project foobar: Command execution failed.
Cannot run program "grunt" (in directory "C:\workspace\foobar\src\main\spa"):
CreateProcess error=2, The system cannot find the file specified -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException:
Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec
(build-spa-bower) on project foobar: Command execution failed.
为了确保，在同一个终端，我执行了这个
Just to be sure, in the same terminal, I have executed this
cd C:\workspace\foobar\src\main\spa
grunt build
...在我发出上面的maven命令的同一个终端中，grunt执行得很好。
... in the same terminal as I issued the maven command above, and grunt executes just fine.
exec-maven-plugin 使用 PATH 环境变量，还是需要告诉我这个可执行文件有其他方式吗？
Does exec-maven-plugin use the PATH environment variable, or does it need to be told that this executable exisst in some other way?
这文档表明 PATH <上的可执行文件应该找到/ code>，所以它让我更进一步。
This documentation suggests that executables on PATH should be found, so it stumps me further.
推荐答案
除了bguiz的答案，哪个会是最好的解决方案，我已经使用Maven配置文件创建了一个解决方法，绕过了这个问题。
In addition to bguiz' answer, which would be the best solution, I've created a workaround using Maven profiles, bypassing the problem.
这是一个临时解决方案直到maven-exec-plugin的bug被修复为止。
This is a temporary solution, until the maven-exec-plugin's bug gets fixed.
