Gradle探索之路（一）

首先我們要安裝gradle并配置環(huán)境變量，參考官網(wǎng)
https://docs.gradle.org/current/userguide/installation.html

1.首先新建目錄

mkdir basic-demo
cd basic-demo
gradle init

然后可以查看到basic-demo目錄下生成了如下文件

build.gradle  gradle/  gradlew*  gradlew.bat  settings.gradle

我們想要完成拷貝文件夾的task,所以可以在當(dāng)前目錄下新建一個(gè)src文件夾，然后在該文件夾下touch一個(gè)文件myFile.txt,然后打開build.gradle,構(gòu)建一個(gè)task任務(wù),
build.gradle

task copy(type:Copy,group:"Custom",description:"Copies source to the dest directory"){
    from "src"
    into "dest"
}

目標(biāo)是將src文件夾下的myFile.txt拷貝到dest文件夾，當(dāng)然dest是自動(dòng)生成的
task編寫完成后即可執(zhí)行該任務(wù)

gradle copy

執(zhí)行成功后我們看下目錄結(jié)構(gòu)

F:\gradledemo\basic-demo>ls
build.gradle  dest/  gradle/  gradlew*  gradlew.bat  settings.gradle  src/

果然生成了dest文件夾，進(jìn)入我們可查看到myFile.txt文件，說(shuō)明這個(gè)task完成了拷貝文件的任務(wù)

壓縮文件
首先需要add base plugin to your build script file ，base插件一定要放到.gradle文件頭部

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目錄下生成了我們壓縮的文件

F:\gradledemo\basic-demo\build\distributions>ls
basic-demo-1.0.zip

Gradle還提供了基于構(gòu)建的豐富的基于Web的視圖，稱為構(gòu)建掃描,通過(guò)--scan

gradle zip --scan

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

https://gradle.com/s/ga3kzf23dvrjw這個(gè)地址就是我們構(gòu)建zip Task的基于web的視圖
通過(guò)瀏覽構(gòu)建掃描，則應(yīng)該能夠輕松找出執(zhí)行了哪些任務(wù)，花費(fèi)了多長(zhǎng)時(shí)間，應(yīng)用了哪些插件等等
