使用Spring Annotation注解导致jar包更新的文件扫描不到

问题出现场景：

由于项目比较大， 分了多个模块， 公共模块都是jar包的方式引入的， 之前使用的maven来管理并生成jar包， 所以没发生过这种情况， 目前的项目没使用maven，所以核心公共包都是更改后直接通过eclipse/myeclipse打包之后丢进去的，今天更新了其中一个包之后，项目启动出现如下错误：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [sundun.fm.service.imp.FmTemplateServiceImp] is defined: expected single bean but found 0: 

具体错误信息如下：

最后究其根本原因，发现是在打包那一环节出现的问题

• 用spring的注解，打包的时候要把Add directory entries选项勾上， 不然jar里面改过的类扫描不到， 启动就会报错

勾上之后再重新打包就没问题了。
