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>
<pluginManagement>
<plugins>
<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):
