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，

 4.0.0

 com.cetc.di
 hellocetc
 0.0.1-SNAPSHOT
 jar

 hellocetc
 http://maven.apache.org



 
  UTF-8
 

 
  
   junit
   junit
   3.8.1
   test
  
 
 
 




  org.apache.maven.plugins
  maven-jar-plugin
  
    1.8
    1.8
    
      
        com.cetc.di.hellocetc.App
        true
      lib/
      

    
    
    
  

  

 

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）：
