Maven Jetty：插件管理器内部执行目标错误org.mortbay.jetty：maven-jetty-plugin：6.1.22：运行'

我已经能够通过Maven的jetty插件本地运行一些Web服务以用于测试目的已经有一段时间了。我能够运行大约7个这样的服务，它运行良好。近日，无需任何配置的变化，我开始收到以下错误：Maven Jetty：插件管理器内部执行目标错误org.mortbay.jetty：maven-jetty-plugin：6.1.22：运行'

下面是从POM配置：

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.mortbay.jetty</groupId> 
      <artifactId>maven-jetty-plugin</artifactId> 
      <configuration> 
       <connectors> 
        <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector"> 
         <port>8083</port> 
        </connector> 
       </connectors> 
      </configuration> 
     </plugin> 
    </plugins> 
</build>

此配置，因为我是能够成功地运行它并没有改变。我尝试更新Maven的版本（从2.0.9到2.2.1），但是这并没有解决任何问题。我也尝试删除.m2/repository/org/mortbay/jetty目录并在构建循环中重新下载，但这也没有解决任何问题。

近日，无需任何配置的变化，我开始收到以下错误[...]

也许你没有改变任何东西......但是，也许你开始使用的新版本maven-jetty-plugin。尝试恢复到以前的版本：

<build> 
    <plugins> 
    <plugin> 
     <groupId>org.mortbay.jetty</groupId> 
     <artifactId>maven-jetty-plugin</artifactId> 
     <version>6.1.21</version> 
     <configuration> 
     <connectors> 
      <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector"> 
      <port>8083</port> 
      </connector> 
     </connectors> 
     </configuration> 
    </plugin> 
    </plugins> 
</build>

其实，市民应该ALWAYS锁定为构建重复性插件版本（即使我不知道这会在这里解决问题）。新的东西可以打破你的构建，你不想让他们失去控制。
