apache网站在国内打开太慢了。因此我将这些有用的资源收集起来,保存在博客中!

Apache Maven Shade Plugin:是一个Maven打包的插件。其官网英文定义如下:This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade

(001)`Shade`官网上的介绍也不多。可能因为其相对比较简单吧。但是,我这个菜鸟仍然很头疼如何配置`Shade`。网上的资料比较少,估计也是认为比较简单吧,没人撰文详细介绍`Shade`。所以,官方提供的例子就成为最有价值的资料了。

(002)结合`Shade`源码,我开始踏上研究如何使用的`Shade`旅程。源码的获得比较简单,为了研究`Shade`可以将其添加到pom.xml的`dependencies`中。当然也可以去官网镜像下载

(003)研究任何`Maven Plugin`之前,都应该先看看这篇插件的介绍 [Guide to Configuring Plug-ins](http://maven.apache.org/guides/mini/guide-configuring-plugins.html),这会让你少走很多弯路(我不会告诉你我是掉坑里了爬起来才知道的)。

(003001)在这篇官方文档里,我首次看到了`Mojo`,这是Maven Plugin使用的一个IOC框架。(当下我并没有去研究Mojo所以知道的有限也许未来会去研究下。有兴趣的朋友可以去搜索下。)

(003002)`Mojo`中的字段是和plugin中的配置对应的,如果对例子中的配置很疑惑,就可以翻开源码中的`Mojo`顺藤摸瓜,找到它们的原理。`Shade`中的`Mojo`就是`ShadeMojo.java`了。
