1 gradle download

gradle-5.6.4-bin.zip .
Gradle historical version released .

2 unzip gradle

Unzip gradle-5.6.4-bin.zip to the local directory D:\dev\gradle5.6.4

3 Add environment variables

GRADLE_HOME

%GRADLE_HOME%\bin

4 Verify that the installation was successful

gradle -v

5 Configure Gradle to use maven local warehouse

Configure gradle to use the jar package of the maven local warehouse, thus saving time and space.
Configure environment variables: GRADLE_USER_HOME
The variable value is the path of the maven local warehouse, such as:
D:\devRepos\mavenRepo

At this point, the files downloaded by Gradle will be placed in the specified warehouse path.

6 gradle configuration global warehouse

.Create a file GRADLE_USER_HOMEin the directory corresponding to the system environment variableinit.gradle

allprojects{
    
    
    repositories {
    
    
        def ALIYUN_REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
        def ALIYUN_JCENTER_URL = 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
        all {
    
     ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
    
    
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2')) {
    
    
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if (url.startsWith('https://jcenter.bintray.com/')) {
    
    
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                    remove repo
                }
            }
        }
        maven {
    
    
            url ALIYUN_REPOSITORY_URL
            url ALIYUN_JCENTER_URL
        }
    }
}

7 Modify the build.gradle of the construction project

Generally, Gradle and maven download dependency packages from the central warehouse mavenCentral () http://repo1.maven.org/maven2/.
Use domestic mirrors:

repositories {
    
     //repositories闭包
	maven {
    
    
		url 'http://maven.aliyun.com/nexus/content/groups/public/'
	}
	mavenLocal() //配置先从本地仓库寻找jar包，优先寻找上一个配置，找到不执行下面的配置
	mavenCentral() //配置从中央仓库寻找
	google() //第三方仓库
	jcenter() //代码托管库：设置之后可以在项目中轻松引用jcenter上的开源项目
}

8 gradle common commands

gradle compile test

#编译(含单元测试)
gradle build

#编译(跳过单元测试)
gradle build -x test

#单元测试
gradle test

#安装到本地maven仓库
gradle install

#清空所有编译、打包生成的文件，会清空build目录
gradle clean

#运行项目
gradle run

#源码打jar包，生成的jar在build/libs目录下
gradle sourcesJar

#生成eclipse结构
gradle eclipse -x :eclipse    

#生成pom.xml文件，在build根目录下。把它复制项目根目录下，即可将gradle方便转成maven项目
gradle createPom

gradle environment installation
