Tomcat启动项目报错:invalid LOC header (bad signature)

一、问题描述

项目用的是Maven构建的，用Tomcat一启动，就报invalid LOC header (bad signature)错误:

出现这种情况的原因就是原因就是某个jar包由于什么原因被破坏了,或者没下载全等等。

二、解决方法:

网上都解决方法是:

方法1、可通过右击项目名 ->  Run as -> Maven test ，这时控制台会报哪个jar包出错。 （也可以打开DOS命令窗口，切换至项目目录，运行mvn test命令，和Eclipse的控制台输出信息一致）


方法2、如果方法1未出现任何错误信息，那么就使用笨办法。打开项目中的pom.xml文件，在自己的Maven本地仓库去查找pom.xml文件中每一个dependency节点所对应的jar包版本。一个一个对比，看看是否都正常下载。 

我这里根本就不行，然后我通过以下命令找出来病因(需要使用tomcat插件):

mvn tomcat7:run

然后把它删除，从新下载就好了。
