How to include external jar dependency to maven project?

Question

While running my app as a Java Application, the included jar in projects Build Path is found and runs without any error. When I try to run the application by executing java -jar myApp.jar the used class from the external jar isn't found.

Exception in thread "main" org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.escomled.blackboard.impl.BlackboardImpl] for bean with name 'blackboard' defined in class path resource [appContext.xml];

如果未通过任何Maven插件将外部jar组合在一起，则可能需要将其添加到类路径中。

java -cp <path to external jar> -jar myApp.jar
