在通过Jenkins构建maven项目时，构建完成后，启动tomcat报错，百思不得其解。记一下处理方法，

解决办法的博文：(https://blog.csdn.net/kevinxxw/article/details/79658400)
打的jar包文件有加密，签名不合法。这是因为在使用Maven打包的时候导致某些包的重复引用，以至于打包之后的META-INF的目录下多出了一些*.SF，.DAS，.RSA文件所致。
在POM文件里加入一些配置，过滤掉这些文件即可：
<configuration>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
