我收到以下错误蚂蚁在控制台在运行码头：使用MVN任务停止命令，权限（java.lang.RuntimePermission exitVM）在执行停止码头与Maven Ant任务未被授予

在搜索对于这个错误，我得到了类似的帖子，

提示设置fork="true"将解决这个问题，但如果已经是我叉设置为true（或者甚至是错误的），我得到这个错误
下面是我的Ant目标调用停止Jetty服务器，
<target name="jetty-stop" fork="true">
<artifact:mvn mavenHome="${maven.home}">
<jvmarg value="-Xmx1024m" />
<arg value="jetty:stop"/>
</artifact:mvn>
</target>
更新：
我也注意到错误消息，同时初始化C3P0相同这一问题提到，
java.security.AccessControlException when using Ant, but runs ok when invoking java from console
同时使用下面的蚂蚁任务启动服务器，
<target name="jetty-start-jdk8">
<delete dir="war/WEB-INF/lib"/>
<artifact:mvn mavenHome="${maven.home}" fork="true">
<jvmarg value="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000" />
<jvmarg value="-javaagent:${jrebel.path}" />
<jvmarg value="-Xbootclasspath/p:C:/Users/admin/AppData/Local/Temp//rebelboot.jar" />
<arg value="compile"/>
<arg value="war:exploded"/>
<arg value="jetty:run"/>
</artifact:mvn>
</target>
上述职位还建议设置fork="true"来解决它。但它已被设置为真。这里可能是什么问题？
