本文介绍了使用maven生成可执行的jar包的方法，分享给大家，具体如下：
从pom的xsi中可以打开描述pom的schema:
可以看到pom中，project的结构：
默认的mvn install生成的jar是不带主类入口的，需要在maven-compile-plugin中设置主类，
4.0.0 com.cetc.di hellocetc0.0.1-SNAPSHOT jar hellocetc http://maven.apache.org UTF-8 junit junit3.8.1 test org.apache.maven.plugins maven-jar-plugin1.8 1.8 com.cetc.di.hellocetc.App truelib/
执行mvn install:
在target目录中，发现jar包已经生成：
用java decompiler，可以看到manifest中已经加入了MainClass：
使用mvn help:effective-pom可以看到pom.xml的完整结构（包括继承而来的属性）：
