windows - 为什么我不能关闭从 Maven 插件嵌入的 tomcat 7？

Question

我正在使用 tomcat7-maven-plugin 2.2 从命令行运行 webapp(我在 Windows 8.1、Java 1.7.0_51 和 Maven 3.2.1 上)。

这是配置(我想很简单):

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>

    <configuration>
        <address>localhost</address>
        <port>8080</port>
        <path>/</path>
        <uriEncoding>UTF-8</uriEncoding>
    </configuration>
</plugin>

我用 mvn tomcat7:run 运行 Maven它正确启动，服务器启动，webapp 加载，我可以与之交互。
我运行 Maven 的命令提示符忙于显示 Tomcat 输出(这对我来说很好):

然后，我想关闭服务器:我运行 mvn tomcat7:shutdown从一个单独的命令提示符，但我得到的是:

[INFO] Scanning for projects...
[INFO]
[INFO] Using the builder org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder with a thread count of 1

[INFO] ------------------------------------------------------------------------
"cmd" non è riconosciuto come comando interno o esterno,
 un programma eseguibile o un file batch.

最后一行是:

"cmd" is not a recognized internal or external command, an executable or a batch file.

我可以从第一个命令提示符中停止 Tomcat Ctrl+C ，但由于我需要将所有这些传递给其他人，我想为他们提供一个脚本来启动 webapp 和一个脚本来停止它。

怎么了？是插件错误吗？是我这边的配置错误吗？

编辑

如果我添加 <fork>true</fork>对于 POM，服务器因以下错误而崩溃:

据我所知，在使用 mvn tomcat7:run 启动 Tomcat 服务器后，您需要使用 Ctrl + c 将其关闭它附加到当前的 Maven 运行。

shutdown 目标用于在例如执行一些测试(集成测试)以干净的方式完成所有工作。
