使用maven生成可执行的jar包的方法

使用maven生成可执行的jar包的方法

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，

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

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）：
