运行storm cluster并创建第一个拓扑。这些是我遵循的步骤
1） 安装maven
2） 已为eclipse安装maven插件
3） 在eclipse中创建新的maven项目，工件名称为stormartifact
4） 它生成了一个文件夹结构和一个pom.xml文件
5） 我更新了pom.xml如下。
6） 我添加了喷口和螺栓在这个链接中指定
https://github.com/storm-book/examples-ch02-getting_started/zipball/master
7） 现在我用命令运行它

mvn exec:java -Dexec.mainClass="TopologyMain" -Dexec.args="src/main/resources/words.txt"

但它抛出了如下错误

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3:java (def
ault-cli) on project stormArtifact: The parameters 'mainClass' for goal org.code
haus.mojo:exec-maven-plugin:1.3:java are missing or invalid -> [Help 1]
