gradle task简单使用方法

gradle命令

语法：gradle task名称
gradle build：执行build任务
gradle -m build：打印执行build任务之前的前序任务顺序
gradle build -info：执行build任务，并打印详细的编译信息

gradle task

/**
**将lib下的app重命名为app.apk并拷贝至build/outputs/apk/release/目录下（打包后文件替换，嘘！）
**/
task CopyAPK(type: Copy){ //task名称是CopyAPK，类型是copy类型(类似继承)，
    from 'libs/app' 
    rename 'app', "app.apk"
    into 'build/outputs/apk/release/'
}

/**
**删除build/outputs/apk/release/app-release.apk，并依赖CopyAPK任务（在执行完CopyAPK之后再执行DeleteAPK）
**/
task DeleteAPK(type: Delete){
    dependsOn CopyAPK
    delete 'build/outputs/apk/release/app-release.apk'
}

gradle安卓任务依赖

project.tasks.whenTaskAdded { theTask ->
if (theTask.name =='assembleRelease') {
assembleRelease.dependsOn DeleteAPK// DeleteAPK之后再执行assembleRelease
    }
}

通过 gradle assembleRelease命令就可以实现，上述task的执行先后顺序（非紧密相连）为：
CopyAPK->DeleteAPK->assembleRelease
