如何通过命令提示符运行Storm Topology类？

Question

嗨，我有一个带有main方法的拓扑类。它启动zookeeper并在eclispe中运行，右键单击run as java application。但是我正在尝试让它能够运行我已经尝试过的批处理文件

java -classpath jar-with-classes-and-dependency.jar com.demo.Topology

但这给了我这样的例外。

Exception in thread "main" java.lang.NoClassDefFoundError:
backtype/storm/generated/AlreadyAliveException
        at java.lang.Class.getDeclaredMethods0(Native Method)
        at java.lang.Class.privateGetDeclaredMethods(Unknown Source)
        at java.lang.Class.getMethod0(Unknown Source)
        at java.lang.Class.getMethod(Unknown Source)
        at sun.launcher.LauncherHelper.getMainMethod(Unknown Source)
        at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) Caused by: java.lang.ClassNotFoundException:
backtype.storm.generated.AlreadyAliveException
        at java.net.URLClassLoader$1.run(Unknown Source)
        at java.net.URLClassLoader$1.run(Unknown Source)

        at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)

我认为这是关于遗漏任何依赖。请帮助运行此拓扑类。

试着像这样跑步...

pathToStorm/bin/storm jar ./target/jar-with-classes-and-dependency.jar com.demo.Topology.

请记住，您应该在执行此步骤之前构建jar。您可以通过在pom.xml文件所在的storm项目中运行mvn clean install来构建jar。
