Maven父子依赖关系

1、Eclipse下Maven的父子结构展示

2、创建父项目，pom文件

<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.curtain</groupId>
  <artifactId>frame</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
  <name>Curtain</name>
  <!--
      打包的时候，执行顺序
      parent：防止所有依赖JAR
      console：自定义的JAR（可以理解为项目的后端代码打包）
      web：放置配置文件、相关页面
  -->
  <modules>
        <module>curtain-parent</module>
        <module>curtain-console</module>
        <module>curtain-web</module>
    </modules>
</project>

3、创建子项目parent，pom文件

<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">
	 <parent>
            <groupId>com.curtain</groupId>
            <artifactId>frame</artifactId>
            <version>0.0.1-SNAPSHOT</version>
          </parent>
          <groupId>com.curtain.frame</groupId>
          <artifactId>curtain-parent</artifactId>
          <packaging>pom</packaging>
        <!--定制属性-->

4、创建子项目console，JAR文件

<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>
  <parent>
    <groupId>com.curtain</groupId>
    <artifactId>frame</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.curtain.frame</groupId>
  <artifactId>curtain-console</artifactId>
</project>

5、创建子项目web，WAR文件

<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>
   <!-- <parent>
        <groupId>com.curtain.farme</groupId>
        <artifactId>curtain-parent</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent> -->
    <parent>
    <groupId>com.curtain</groupId>
    <artifactId>frame</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.curtain.farme</groupId>
  <artifactId>curtain-web</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  <name>curtain-web</name>
    <dependencies>
   </dependencies>
  <!--编译并运行tomcat: war:exploded tomcat7:run -->
    <!--打包代码： install -->
    <build>
        <plugins>
			<plugin>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<!-- class文件会自动打JAR包 -->
					<archiveClasses>false</archiveClasses>
					<failOnMissingWebXml>false</failOnMissingWebXml>
					<!--覆盖-->
					<overlays>
						<overlay>
							<groupId>com.curtain.farme</groupId>
							<artifactId>curtain-web</artifactId>
						</overlay>
					</overlays>
				</configuration>
			</plugin>
		</plugins>
    </build>
</project>

6、运行父项目的POM文件，打包效果

注意：

1、新建Maven项目，勾选这个，免去选择模板

2、想要显示父子结构，除了要按照这样添加POM之外，还需要在父项目的POM中设置

2.1Add是添加已存在的Maven项目在父项目下

2.2Create是创建一个新的Maven项目在父项目下
