maven build jar包的时候，在当前的lib目录自动引入依赖包

<build>
<finalName>your-project-name</finalName>
<resources>
<resource>
<targetPath>${project.build.directory}/classes</targetPath>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
</resources>

第一个插件maven-jar-plugin负责生成指定入口的可执行JAR文件。同时在manifest.mf文件里写入入口函数信息和classpath。本例中是吧classpath设置为lib目录。

第二个插件maven-dependency-plugin负责创建lb目录，同时把需要依赖的jar包全部复制进去。
