Maven搭建多子项目工程

1.创建main工程

1	mvn archetype:generate -DgroupId=com.neusoft.lemon -DartifactId=lemon-main -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

check code

2.修改main工程

删除src目录，修改pom.xml 中 <packaging>jar</packaging> 替换为pom

<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/maven-v4_0_0.xsd">
 <modelVersion>4.0.0</modelVersion>
 <groupId>com.neusoft.lemon</groupId>
 <artifactId>lemon-main</artifactId>
 <packaging>pom</packaging>
 <version>1.0-SNAPSHOT</version>
 <name>lemon-main</name>
 <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
     <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

3.创建child工程

在main工程的目录下创建

1	mvn archetype:generate -DgroupId=com.neusoft.lemon -DartifactId=lemon-server -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

这时可以看见main工程下pom中多了几个配置项

<?xml version="1.0" encoding="UTF-8"?>
<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/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.neusoft.lemon</groupId>
  <artifactId>lemon-main</artifactId>
  <packaging>pom</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>lemon-main</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <!-- 多出来的配置项，是创建子项目时自动添加的，我创建了2个子项目 -->
  <modules>
    <module>lemon-server</module>
    <module>lemon-client</module>
  </modules>
</project>

修改子项目的pom文件，去掉<groupId>和<version> 子项目会继承父项目的，添加 <packaging>jar</packaging>。并添加不同子项目的依赖。

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.neusoft.lemon</groupId>
    <artifactId>lemon-main</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  
  <artifactId>lemon-server</artifactId>
  <packaging>jar</packaging>
  
  <name>lemon-server</name>
  <url>http://maven.apache.org</url>
  
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    
    <dependency>
      <groupId>com.neusoft.lemon</groupId>
      <artifactId>lemon-core</artifactId>
      <version>${project.version}</version>
    </dependency>
  
  </dependencies>
</project>

4.完毕

导入Idea中。如下图：

PS:子项目已可以镶嵌子项目。
