java.lang.NoClassDefFoundError与Intellij和Maven [英] java.lang.NoClassDefFoundError with Intellij And Maven
本文介绍了java.lang.NoClassDefFoundError与Intellij和Maven的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用Maven 3.0.5和Intellij 14.0.2，并且Maven不在我的项目的calsspath中复制所需的Jar，因此我正在手动复制它并尝试执行我的项目的主类，这使我跟随错误:
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:

我知道它非常普遍，并在StackOverflow上找到了很多解决方案，但是没有一个对我有用. 任何帮助将不胜感激.
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.

推荐答案
风暴库的范围是provided，这意味着在运行时您必须自己提供依赖项(通常在部署时使用)到应用程序服务器的应用程序，并且该库已在应用程序服务器中).对于独立应用程序，请将范围更改为compile(或将其删除，因为默认值为compile).然后，在运行应用程序时，JAR应该位于类路径中.
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 compile is the default). Then the JAR should be in the classpath when running the application.
