我是用maven多模块项目，有以下几个子项目
admin（后台，springmvc）
service（服务层，只有源码）
data（数据访问层，只有源码）
config（只有配置文件，mysql.yml）
admin依赖service，service依赖data，data依赖config，在admin目录下面打包，做法是将config.jar用unpack，将里面的mysql.yml复制到admin的resource下面，
admin的源码，resource，依赖的lib全都各自独立出来，在copy-dependencies到lib目录时，将config排除（因为已经复制了里面的配置文件）。现在把这些东西放到服务器上运行，启动tomcat时候会出现一个WARN，但是不影响启动，网站也能正常访问
下面是admin的打包方式

虽然是个WARN，不影响程序运行，但是我一直想找出来哪里出问题了，tomcat怎么就会去扫描一个不存在lib目录下的jar呢。
ps：tomcat是spring boot内置的容器
