上项目结构图：

idea里面一个project其实相当于eclipse的一个workspace,这样一来就很好理解了，我们新建了两个module,相当于eclipse的两个项目工程

主要看配置：build.gradle和根项目settings.gradley以及class

action:

group 'cn.sawshaw'version '1.0-SNAPSHOT'apply plugin: 'java'sourceCompatibility = 1.8repositories {    mavenCentral()}dependencies {    compile project(":service")    testCompile group: 'junit', name: 'junit', version: '4.12'}

 

package action;import service.SayHello;public class HelloAction {   public String helloAction(String name){       return new SayHello().sayHello(name);   }   public static void main(String[] args){       String result=new SayHello().sayHello("小明");       System.out.println(result);   }}

　　

Service:

group 'cn.sawshaw'version '1.0-SNAPSHOT'apply plugin: 'java'sourceCompatibility = 1.8repositories {    mavenCentral()}dependencies {    testCompile group: 'junit', name: 'junit', version: '4.12'}

 

package service;public class SayHello {    public String sayHello(String name){        System.out.print("service sayHello start .");        return "Hello:"+name;    }}

　

根项目User:

group 'cn.sawshaw'version '1.0-SNAPSHOT'apply plugin: 'java'sourceCompatibility = 1.8repositories {    mavenCentral()}dependencies {    compile project(":action")    testCompile group: 'junit', name: 'junit', version: '4.12'}

　

rootProject.name = 'user'include 'action'include 'service'

 

package test;import action.HelloAction;public class Test1 {    public static void main( String[] args ){      String result= new HelloAction().helloAction("lily");      System.out.println(result);    }}

　　

可以看出Action依赖Service,User依赖Action　　

eclipse自带了可以构建父子项目工具Gradle STS Project
