• 在B站看到一个讲解Gradle的非常棒的视频： https://www.bilibili.com/video/BV1DE411Z7nt?p=1

练习一

• build.gradle

//System.out.println("hello, world!")
//println "hello world!"
//
//task("hello_world") {
//    println "configure"
//    doLast {
//        println("Executing task")
//    }
//}

afterEvaluate {
    println "after evaluate"
}

task('first') {
    println("configuring")
    doLast { println "I'm first task"}
}

class MyAwesomePlugin implements Plugin<Project> {
    @Override
    void apply(Project project) {
        (0..<10).each {i ->
            project.task("task" + i) {
                if (i % 2 == 0) {
                    dependsOn('first')
                }
                def captureI = i
                doLast { println "task $captureI" }
            }
        }
    }
}



//(0..<10).each {i ->
//    task("task" + i) {
//        if (i % 2 == 0) {
//            dependsOn('first')
//        }
//        def captureI = i
//        doLast { println "task $captureI" }
//    }
//}

//apply ([plugin: 'java'])
//apply plugin: 'groovy'
//apply plugin: 'checkstyle'

apply plugin: MyAwesomePlugin

// gradle script plugin
//apply plugin: 'http://myserver.com/my-script'

练习二

• build.gradle

import org.apache.commons.lang3.StringUtils

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        mavenCentral()
    }

    dependencies {
        classpath group: 'org.apache.commons', name: 'commons-lang3', version: '3.12.0'
        //implementation 'org.apache.commons:commons-lang3:3.12.0'
    }
}

apply plugin: 'java'

repositories {
    maven { url 'https://maven.aliyun.com/repository/public/' }
    mavenCentral()
}

dependencies {
    implementation group: 'org.apache.commons', name: 'commons-lang3', version: '3.12.0'
    //implementation 'org.apache.commons:commons-lang3:3.12.0'
}

if (StringUtils.isNoneEmpty("")) {}

• 这个讲师讲解的特别棒，值得反复回味
