提问by tom
I am working with Maven 3.0.5 and Intellij 14.0.2 and Maven is not copying the required Jars in my project's calsspath so I am copying it manually and trying to exccute the main class of my project it is throwing me following error:
我正在使用 Maven 3.0.5 和 Intellij 14.0.2 并且 Maven 没有在我的项目的 calsspath 中复制所需的 Jars，所以我手动复制它并尝试执行我的项目的主类它抛出以下错误：

I know its very common and found a bunch of solutions at StackOverflow but none of them are working for me. Any help will be appreciated.
我知道它很常见，并在 StackOverflow 上找到了一堆解决方案，但没有一个对我有用。任何帮助将不胜感激。

The scope of the storm library is provided, which means, that at runtime you have to provide the dependency yourself (this is usually used, when you deploy an application to an application server and the library is already in the appserver). For a standalone application, change the scope to compile(or remove it, since compileis the default). Then the JAR should be in the classpath when running the application.
Storm 库的范围是provided，这意味着在运行时您必须自己提供依赖项（这通常用于将应用程序部署到应用程序服务器并且库已经在应用程序服务器中）。对于独立应用程序，将范围更改为compile（或删除它，因为这compile是默认设置）。然后在运行应用程序时 JAR 应该在类路径中。

Probably that is because you are importing stormartifact instead of storm-core.
可能那是因为您正在导入stormartifact 而不是storm-core.
<dependency>
<groupId>org.apache.storm</groupId>
<artifactId>storm-core</artifactId>
<version>0.9.4</version>
</dependency>
