Task :tasks———————————————————— Tasks runnable from root project

To see all tasks and more detail, run gradlew tasks –all可以看到,这里有很多的task.比如我们在命令行执行gradlew clean就是clean.执行gradlew installDebug就是构建debug项目然后安装到手机上. 3.2 编写task 书写task非常简单,比如我们在根目录的build.gradle中加入一个hello的task task hello() {println hello world//将给定的闭包 添加到此task操作链表的开头doFirst {println hello task doFirst}doLast {println hello task doLast} }然后在命令行执行gradlew hello,输出如下 setting 开始配置 setting 配置完成 Configure project : 根build.gradle 开始配置 hello world 根build.gradle 配置完成 Configure project :app app build.gradle 开始配置 app build.gradle 配置完成 Task :hello hello task doFirst hello task doLast它会先配置完成,才会执行.在一个task内部其实拥有一个action列表,执行的时候其实就是执行这个列表,它的类型是一个List.上面的doFirst和doLast就是创建action的两个方法,文档.doFirst是在最开始执行,doLast是在最后执行,大括号里面传入的是闭包. 3.3 task执行顺序 task是有执行顺序的,在创建完Android项目之后,根目录下的build.gradle中,有一个clean的task.这个是AS自动给我们生成的. task clean(type: Delete) {delete rootProject.buildDir }我们先在根目录下创建test.txt文件,然后我们在这个task中做一些改动,执行到clean这个task时删除根目录下的test.txt文件. task clean(type: Delete) {delete rootProject.buildDirdoLast {def file new File(test.txt)delete fileprintln 清理} }然后我们在hello这个task的下面写上 hello.dependsOn clean 这样就表示hello这个task依赖clean这个task,当执行hello这个task时需要先执行clean. 我们在命令行执行gradlew hello看看是不是这样.我执行之后它的输出是 Task :clean 清理 Task :hello hello task doFirst hello task doLast 先执行clean,再执行hello这个task.而且还看到test.txt文件被删除(如果看到没删除,刷新一下看看)了,那么说明确实是clean先执行. 这个顺序有什么用?其实是很有用的,比如执行安装task的时候,肯定会先执行编译,打包这些步骤. 3.4 自带 gradle task 当我们在AS中创建Android项目的时候,默认会带一些Android的一些gradle task,这些task都是gradle和Android Gradle Plugin给我们创建好的,可以直接用. 比如我们上面使用到的gradlew clean是用来清理项目的.和编译相关的task主要有build和assemble其中build依赖assemble也就是说执行build之前会先执行assemble。在Android上会根据buildType和productFlavor的不同自动创建多个assembleXxx任务如assembleDebugassembleRelease等assemble会依赖所有的assembleXxx任务也就是说执行assemble会先执行assembleDebugassembleRelease等一系列的assemble任务。 如果想看Android Gradle Plugin源码,可以在app/build.gradle中的dependencies下面引入 compileOnly com.android.tools.build:gradle:3.5.2然后就可以在项目的External Libraries中看到该jar的源码,
比如clean这个task是在com.android.build.gradle.tasks.CleanBuildCache.java里面定义的 TaskAction public void clean() throws IOException {Preconditions.checkNotNull(buildCache, buildCache must not be null);buildCache.delete(); }通过查询gradle官方文档可知,TaskAction的作用:Marks a method as the action to run when the task is executed. 将方法标记为执行任务时要运行的动作.
