Maven shade插件没有将依赖项推送到.jar

Question

我之前问了一个question，那就是询问如何让maven自动将我的依赖源编译到我的build的.jar中，然后我被引导到Maven Shade插件，但是我似乎无法看到让它工作。构建完全没有变化，我已经清理过 - ＆gt;更新 - ＆gt;几次重建项目。

这是我的pom.xml

不确定我做错了什么，编译的结果是

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 3.229 s
[INFO] Finished at: 2014-12-03T10:22:45-06:00
[INFO] Final Memory: 16M/93M
[INFO] ------------------------------------------------------------------------

并且文件大小约为80kb，添加了依赖项大约为5mb（我必须手动完成，这很烦人）

编辑：请注意，eclipse将<plugin>放在<pluginManagement>之外，我认为这可能是问题并手动移动，但它没有改变任何东西
