本文向大家介绍使用maven生成可执行的jar包的方法,包括了使用maven生成可执行的jar包的方法的使用技巧和注意事项,需要的朋友参考一下

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,

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 <modelVersion>4.0.0</modelVersion>

 <groupId>com.cetc.di</groupId>
 <artifactId>hellocetc</artifactId>
 <version>0.0.1-SNAPSHOT</version>
 <packaging>jar</packaging>

 <name>hellocetc</name>
 <url>http://maven.apache.org</url>



 <properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 </properties>

 <dependencies>
  <dependency>
   <groupId>junit</groupId>
   <artifactId>junit</artifactId>
   <version>3.8.1</version>
   <scope>test</scope>
  </dependency>
 </dependencies>
 
 
<build>

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <configuration>
    <source>1.8</source>
    <target>1.8</target>
    <archive>
      <manifest>
        <mainClass>com.cetc.di.hellocetc.App</mainClass>
        <addClasspath>true</addClasspath>
      <classpathPrefix>lib/</classpathPrefix>
      </manifest>

    </archive>
    <classesDirectory>
    </classesDirectory>
  </configuration>
</plugin>
</plugins>  
</pluginManagement>
</build> 
</project>

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):
