首先我们要安装gradle并配置环境变量，参考官网
https://docs.gradle.org/current/userguide/installation.html
1.首先新建目录
mkdir basic-demo
cd basic-demo
gradle init
然后可以查看到basic-demo目录下生成了如下文件
build.gradle gradle/ gradlew* gradlew.bat settings.gradle
我们想要完成拷贝文件夹的task,所以可以在当前目录下新建一个src文件夹，然后在该文件夹下touch一个文件myFile.txt,然后打开build.gradle,构建一个task任务,
build.gradle
task copy(type:Copy,group:"Custom",description:"Copies source to the dest directory"){
from "src"
into "dest"
}
目标是将src文件夹下的myFile.txt拷贝到dest文件夹，当然dest是自动生成的
task编写完成后即可执行该任务
gradle copy
执行成功后我们看下目录结构
F:\gradledemo\basic-demo>ls
build.gradle dest/ gradle/ gradlew* gradlew.bat settings.gradle src/
果然生成了dest文件夹，进入我们可查看到myFile.txt文件，说明这个task完成了拷贝文件的任务
压缩文件
首先需要add base plugin to your build script file ，base插件一定要放到.gradle文件头部
plugins {
id "base"
}
task zip(type:Zip, group: "Archive", description: "Archives sources in a zip file") {
from "src"
archiveFileName = "basic-demo-1.0.zip"
}
然后即可看到build/distributions目录下生成了我们压缩的文件
F:\gradledemo\basic-demo\build\distributions>ls
basic-demo-1.0.zip
Gradle还提供了基于构建的丰富的基于Web的视图，称为构建扫描,通过--scan

gradle zip --scan
F:\gradledemo\basic-demo>gradle zip --scan

通过浏览构建扫描，则应该能够轻松找出执行了哪些任务，花费了多长时间，应用了哪些插件等等
