IDEA利用Maven将依赖的第三方jar包打入一个jar包

在我利用Maven构建好一个工程后，在IDEA的Maven Projects里双击package，发现打出的jar包里没有所要依赖的jar包，于是又在IDEA控制台执行path/to/maven/bin/mvn assembly:assembly命令后，发现又一个个Download很多依赖的jar包，而这些jar包我原先就已经下好了，此时打包的时间很长很长，以至于我无法忍受。（此时pom.xml中已经有maven-scala-plugin、maven-compiler-plugin、maven-assembly-plugin、maven-surefire-plugin这些plugin）

经过一番搜寻，在pom.xml中添加maven-shade-plugin，最终的pom.xml如下：

添加后等待Maven加载完，再次点击package，不一会儿Maven就打包完成，会打成两个jar包，一个是无依赖的jar即original-boya-1.0-SNAPSHOT.jar；一个是有依赖的jar即boya-1.0-SNAPSHOT.jar，里面包括了所依赖的其他jar包
