（03）maven项目分模块开发，子项目继承自父项目，打包运行方法

　　现在有一个项目结构如下：

　　父项目project

<modelVersion>4.0.0</modelVersion>

<groupId>com.xxx.xxx</groupId>
<artifactId>project</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
 
<dependencyManagement>
      <dependencies>
        <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>Brussels-SR4</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
      </dependencies>
 </dependencyManagement> 

 <modules>
      <module>../projectA</module>
      <module>../projectB</module>
      <module>../projectC</module>
 </modules>

　　子项目projectA继承自父项目project

<modelVersion>4.0.0</modelVersion>

<artifactId>projectA</artifactId>
<parent>
    <groupId>com.xxx.xxx</groupId>
    <artifactId>project</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../project</relativePath>
</parent> 
  
<dependencies>
    ... ...
</dependencies>

　　子项目projectB继承自父项目project，同时引入了projectA做为依赖

<modelVersion>4.0.0</modelVersion>

<artifactId>projectB</artifactId>
<parent>
    <groupId>com.xxx.xxx</groupId>
    <artifactId>project</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../project</relativePath>
</parent> 
  
<dependencies>
    <dependency> 
        <groupId>com.xxx.xxx</groupId>
        <artifactId>projectA</artifactId>
        <version>1.0.0-SNAPSHOT</version>
    </dependency>
    ... ...
</dependencies>        

　　子项目projectC继承自父项目project，同时引入了projectB做为依赖

<modelVersion>4.0.0</modelVersion>

<artifactId>projectC</artifactId>
<parent>
    <groupId>com.xxx.xxx</groupId>
    <artifactId>project</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../project</relativePath>
</parent> 
  
<dependencies>
    <dependency> 
        <groupId>com.xxx.xxx</groupId>
        <artifactId>projectB</artifactId>
        <version>1.0.0-SNAPSHOT</version>
    </dependency>
    ... ...
</dependencies>   

　　现在要打包，直接在project上执行clean compile package打出的包无法运行，需要修改projectC（客户写的源码）的pom.xml文件

... ...
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>1.3.3.RELEASE</version>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
    <finalName>demo</finalName>
</build>        

　　然后在project上执行上述命令，打出的jar名字是demo.jar，运行：java -jar demo.jar即可
