# maven打可执行jar包 #

首先需要知道如何建立一个maven项目：

mvn archetype:generate -DarchetypeCatalog=internal

然后修改pom文件

1.      <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.xueyoucto.xueyou</groupId>
        
        <artifactId>MyFirstMavenProject</artifactId>
        
        <version>1.0-SNAPSHOT</version>
        
        <packaging>jar</packaging>
        
        
        <name>MyFirstMavenProject</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>
        
        
        
        <dependency>
        
        <groupId>org.apache.commons</groupId>
        
        <artifactId>commons-lang3</artifactId>
        
        <version>3.4</version>
        
        </dependency>
        
        </dependencies>
        
        <build>
        
        <plugins>
        
        <plugin>
        
        <groupId>org.apache.maven.plugins</groupId>
        
        <artifactId>maven-compiler-plugin</artifactId>
        
        <configuration>
        
        <source>1.8</source>
        
        <target>1.8</target>
        
        <encoding>utf-8</encoding>
        
        </configuration>
        
        </plugin>
        
        <plugin>
        
        <artifactId>maven-assembly-plugin</artifactId>
        
        <version>3.0.0</version>
        
        <configuration>
        
        <archive>
        
        <manifest>
        
        <mainClass>com.xueyoucto.xueyou.App</mainClass>
        
        </manifest>
        
        </archive>
        
        <descriptorRefs>
        
        <descriptorRef>jar-with-dependencies</descriptorRef>
        
        </descriptorRefs>
        
        </configuration>
        
        <executions>
        
        <execution>
        
        <id>make-assembly</id> 
        
        <phase>package</phase> 
        
        <goals>
        
        <goal>single</goal>
        
        </goals>
        
        </execution>
        
        </executions>
        
        </plugin>
        
        </plugins>
        
        </build>
        
        
        
        </project>
    
      
    其中：

1.      <plugin>
        
        <groupId>org.apache.maven.plugins</groupId>
        
        <artifactId>maven-compiler-plugin</artifactId>
        
        <configuration>
        
        <source>1.8</source>
        
        <target>1.8</target>
        
        <encoding>utf-8</encoding>
        
        </configuration>
        
        </plugin>
    
     
2.

这段是负责编译的时候使用jdk的版本和编码格式。

<plugin>
    
    <artifactId>maven-assembly-plugin</artifactId>
    
    <version>3.0.0</version>
    
    <configuration>
    
    <archive>
    
    <manifest>
    
    <mainClass>com.xueyoucto.xueyou.App</mainClass>
    
    </manifest>
    
    </archive>
    
    <descriptorRefs>
    
    <descriptorRef>jar-with-dependencies</descriptorRef>
    
    </descriptorRefs>
    
    </configuration>
    
    <executions>
    
    <execution>
    
    <id>make-assembly</id> 
    
    <phase>package</phase> 
    
    <goals>
    
    <goal>single</goal>
    
    </goals>
    
    </execution>
    
    </executions>
    
    </plugin>

这段有两个功能，一个是设置Main函数，一个是在jar包中引入依赖的jar包。

下面是使用mvn package后生成的jar包。
