Gradle任务执行

• 先执行配置阶段的语句，即每个Task闭包中doFirst和doLast之外的语句
• 再执行执行阶段的语句，即每个Task闭包中doFirst和doLast之内的语句
• 在build.gradle(:app)的Project级别文件下创建MyProjectTask

task MyProjectTask {
    println "MyProjectTask"
    doFirst {
        println '<--------Task myProjectTask start-------->'
    }

    doLast {
        println '<--------Task myProjectTask end-------->'
    }
}

• 在build.gradle(:app)的App级别文件下创建MyAppTaskA，MyAppTaskB

task MyAppTaskA {
    println "Execute MyAppTaskA" 

    doFirst {
        println '<--------Task MyAppTaskA start-------->'
    }

    doLast {
        println '<--------Task MyAppTaskA end-------->'
    }
}

task MyAppTaskB {
    println "Execute MyAppTaskB"

    doFirst {
        println '<--------Task MyAppTaskB start-------->'
    }

    doLast {
        println '<--------Task MyAppTaskB end-------->'
    }
}

• 在build.gradle(:mylibrary)的Module级别文件下创建MyLibraryTaskA

task MyLibraryTaskA {
    println "Execute MyLibraryTaskA"

    doFirst {
        println '<--------Task MyLibraryTaskA start-------->'
    }

    doLast {
        println '<--------Task MyLibraryTaskA end-------->'
    }
}

• Android Studio Terminal 执行./gradlew MyProjectTask
  • 所有App级别和Module级别的Task任务的配置阶段都会执行
  • 最后执行MyProjectTask的执行阶段

PS E:\gradleProject> ./gradlew MyProjectTask

> Configure project :
MyProjectTask

> Configure project :app
Execute MyAppTaskA
Execute MyAppTaskB

> Configure project :mylibrary
Execute MyLibraryTaskA

> Task :MyProjectTask
<--------Task myProjectTask start-------->
<--------Task myProjectTask end-------->

• Android Studio Terminal 执行./gradlew MyAppTaskA
  • 所有App级别和Module级别的Task任务的配置阶段都会执行
  • 最后执行MyAppTaskA的执行阶段

PS E:\gradleProject> ./gradlew MyAppTaskA

> Configure project :

Gradle任务依赖

参数依赖

// Task声明时参数依赖具体的Task(dependsOn: ['Task名称'])
task MyAppTaskB(dependsOn: ['MyAppTaskA']) {
    println "Execute MyAppTaskB"

    doFirst {
        println '<--------Task MyAppTaskB start-------->'
    }

    doLast {
        println '<--------Task MyAppTaskB end-------->'
    }
}

• Android Studio Terminal 执行./gradlew MyAppTaskB
  • 所有App级别和Module级别的Task任务的配置阶段都会执行
  • MyAppTaskB会在依赖的MyAppTaskA之后执行

PS E:\gradleProject> ./gradlew MyAppTaskB

> Configure project :
MyProjectTask

> Configure project :app
Execute MyAppTaskA
Execute MyAppTaskB

> Configure project :mylibrary
Execute MyLibraryTaskA

> Task :app:MyAppTaskA
<--------Task MyAppTaskA start-------->
<--------Task MyAppTaskA end-------->

> Task :app:MyAppTaskB
<--------Task MyAppTaskB start-------->
<--------Task MyAppTaskB end-------->
