Installation

Gradle runs on all major operating systems and requires only a Java JDK or JRE version 7 or higher to be installed. To check, run java -version:

$ java -version
java version "1.8.0_121"

Step 1. Download the latest Gradle distribution

download url : https://gradle.org/releases/
提供了二进制包和完整包（包含User Manual、API Javadoc、DSL Reference）

Step 2. Unpack the distribution

Create a new directory C:\Gradle with File Explorer.

Open a second File Explorer window and go to the directory where the Gradle distribution was downloaded. Double-click the ZIP archive to expose the content. Drag the content folder gradle-4.1 to your newly created C:\Gradle folder.

Alternatively（另外） you can unpack the Gradle distribution ZIP into C:\Gradle using an archiver tool of your choice.

Step 3. Configure your system environment

In File Explorer right-click on the This PC (or Computer) icon, then click Properties -> Advanced System Settings -> Environmental Variables.

Under System Variables select Path, then click Edit. Add an entry for C:\Gradle\gradle-4.1\bin. Click OK to save.

Step 4. Verify your installation

Open Windows command prompt and run gradle -v to run gradle and display the version,
e.g.:

$ gradle -v
Gradle 4.1

注意：不同窗口下命令的执行
dos: C:\Users\14009\Desktop\basic-demo>gradlew properties
gitbash: $ ./gradlew properties

Building Java Applications

$ mkdir java-demo
$ cd java-demo
$ gradle init --type java-application

build.gradle 中添加 apply plugin: ‘idea’
执行命令 gradle idea
用 IntelliJ IDEA打开就可以开始编码

Building Java Libraries

$ mkdir building-java-libraries
$ cd building-java-libraries
$ gradle init --type java-library

Building Java Web Applications

1.0 Create the structure of a web application

create the following file structure for a project called webdemo:

Sample project layout

webdemo/
    src/
        main/
            java/
            webapp/
        test
            java/

2.0 Add a Gradle build file

Add a file called build.gradle to the root of the project, with the following contents:

build.gradle

plugins {
    id 'java'
    id 'war'
}

repositories {
    jcenter()
}

dependencies {
    providedCompile 'javax.servlet:javax.servlet-api:3.1.0' testCompile 'junit:junit:4.12' 
}

It is a good practice to generate a Gradle wrapper for the project by executing the wrapper task:

$ gradle wrapper --gradle-version=4.0
