Maven获取工程相关仓库的源码和javadoc方法

 背景

编写程序和研读代码时，离不开仓库的源码和javadoc，如何将相关文档添加到工程中非常重要。

获取方法

进入工程的根目录，运行下列命令：

mvn dependency:sources -DdownloadSources=true -DdownloadJavadocs=true
 
 Maven将开始下载源码与javadoc相关jar文件，下载完成后，会提示最终下载到的source情况：

在Eclipse中通过点击工程-->右键-->Maven-->Update Project，来更新工程；之后，就可以在工程中看到源码和帮助信息。

参数介绍

-DdownloadSources=true：   下载源代码jar

-DdownloadJavadocs=true： 下载javadoc包
