maven-shade-plugin

有时候，我们需要将所有配置文件和依赖库文件全部放在一个jar包中，运维的同事只需要执行java-jar batch.jar即可完成启动。虽然使用maven-assembly-plugin也可以做到这一点，但是在读取配置文件的时候有可能会遇到一些问题，这个时候，我们可能需要使用到maven-shade-plugin这个插件，经笔者实践按照如下示例用法配置确实可用；当然本示例配置了mainClass，直接执行java-jar batch.jar确实没问题，但如果执行java com.fastjrun.demospring4.BatchInit-classpath batch.jar也是可以的。
