如何打包源码，并将源码包与jar包一同发布

需要在要发布的pom项目里的pom.xml里添加如下内容: 

<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.company-name</groupId>
	<artifactId>project-name</artifactId>
	<version>0.1.0</version>
	<packaging>pom</packaging>
    <name>INPUT NAME</name>
	<modules>
		<module>sub-proj1</module>
		<module>sub-proj2</module>
		<module>sub-proj3</module>
	</modules>
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-resources-plugin</artifactId>
				<version>2.5</version>
				<configuration>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>
			<plugin>

				<version>2.5.1</version>
				<configuration>
					<source>1.6</source>
					<target>1.6</target>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>
			<!--   要将源码放上去，需要加入这个插件    -->
			<plugin>  
				<groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-source-plugin</artifactId>  
                <version>2.1</version>  
                <configuration>  
                    <attach>true</attach>  
                </configuration>  
                <executions>  
                    <execution>  
                        <phase>compile</phase>  
                        <goals>  
                            <goal>jar</goal>  
                        </goals>  
                    </execution>  
                </executions>  
            </plugin>   
		</plugins>
	</build>
</project>

    配置中指定了phase为compile，意思是在生命周期compile的时候就将源文件打包，即只要执行的mvn命令包括compile这一阶段，就会将源代码打包。同样，phase还可以指定为package、install等等。
### 单独的打源码包可执行：mvn source:jar（会生成在target目录下） 
### 打包同时生成源码包：mvn clean source:jar install
