ClassNotFound异常：Eclipse中的Maven无法正常工作

我有以下pom.xml 

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

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

我收到的错误如java.lang.ClassNotFoundException

我猜我在Eclipse中的项目根本没有加载任何Maven依赖项。

如果我从命令行运行相同的项目，那么它的工作。

但如果我删除了以下行，那么它在Eclipse中完美运行。

<outputFileNameMapping>${outputFileNameMapping}</outputFileNameMapping>

有人可以帮忙吗？

另外，我已经为类'org.zkoss.zk.ui.http.HttpSessionListener'添加了依赖项，但它仍然给了我这个错误。

尝试从命令提示符编译代码，如果您得到相同的错误，则表示缺少依赖项。如果它工作正常，你需要执行mvn eclipse：eclipse，并刷新你的项目
