**一 项目名称**

ToDo应用程序，只实现添加待办事项。

**二 发布方式**

**Java应用程序版**

**三 开发过程**

1 创建Gradle项目todo

创建过程参考： [https://blog.csdn.net/chengqiuming/article/details/103102103][https_blog.csdn.net_chengqiuming_article_details_103102103]

2 项目自动生成build.gradle，代码如下

// 创建项目时填写
    group 'com.imooc.gradle'
    // 指定生成的编译文件版本，默认打成jar包
    version '1.0-SNAPSHOT'
    
    // 使用的插件
    apply plugin: 'java'
    // 指定Java编译版本
    sourceCompatibility = 1.8
    
    // 使用中央仓库
    repositories {
        mavenCentral()
    }
    
    
    dependencies {
        // 该依赖用于测试阶段
        testCompile group: 'junit', name: 'junit', version: '4.12'
    }

它是项目的构建脚本。

**五 编写代码**

1 App

package com.immoc.gradle.todo;
    
    
    import java.util.Scanner;
    
    
    public class App {
        public static void main(String[] args){
            int i = 0;
            Scanner scanner = new Scanner(System.in);
            while(++i>0){
                System.out.println(i+". Please input todo item name:");
                TodoItem item = new TodoItem(scanner.nextLine());
                System.out.println(item);
            }
        }
    }

2 TodoItem

package com.immoc.gradle.todo;
    
    
    public class TodoItem {
        private String name;
    
    
        public TodoItem( String name ) {
            this.name = name;
        }
    
    
        public String getName() {
            return name;
        }
    
    
        public void setName( String name ) {
            this.name = name;
        }
    
    
        public boolean isHasDone() {
            return hasDone;
        }
    
    
        public void setHasDone( boolean hasDone ) {
            this.hasDone = hasDone;
        }
    
    
        @Override
        public String toString() {
            return "TodoItem{" +
                    "name='" + name + '\'' +
                    ", hasDone=" + hasDone +
                    '}';
        }
    
    
        private boolean hasDone;
    
    
    }

**六 关于编译**

目前我们只关心将源文件打包成jar

点击jar，编译结果如下：

16:45:26: Executing task 'jar'...
    
    
    :compileJava
    :processResources NO-SOURCE
    :classes
    :jar
    
    
    BUILD SUCCESSFUL in 1s
    2 actionable tasks: 2 executed
    16:45:28: Task execution finished 'jar'.

下面是编译结果

**七 测试**
