运行Maven项目（Eclipse）时出现NoClassDefFoundError

Question

在我的Maven项目中，我为MongoDB Java驱动程序添加了一个依赖项。但是当我尝试运行该程序时，它会产生：

java.lang.NoClassDefFoundError: com/mongodb/MongoClient
    com.therapy.Test.doGet(Test.java:27)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:624)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:731)
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

因此，我右键单击我的项目，然后转到Run As -> Run Congfigurations... -> Classpath，发现没有添加MongoDB jar：

将我的MongoDB jar添加到Classpath选项卡可以解决NoClassDefFoundError吗？如果是这样，我该怎么做？

我的pom.xml文件，如果需要：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
