1. 安装 点击"Install Gradle"
安装1.PNG
2.下载 点击Binary-only
安装2.PNG
3.添加到环境变量Path中
//解压 复制到bin的路径 添加到环境变量中
C:\tools\gradle-6.7.1\bin
4.打开IDEA新建Gradle工程，选择java
如果使用的是其他版本的Gradle，可以配置成本地的Gradle，打开gradle-wrapper.properties distributionUrl 修改为
distributionUrl=file:///C:/tools/gradle-6.7.1-bin.zip
5.将build.gradle修改为build.gradle.kts
环境配置好后，可以在build.gradle.kts写一些配置
6.配置Gradle支持编译Kotlin
在build.gradle.kts文件中配置如下，这样编写kotlin代码也可以编译执行
plugins {
application
kotlin("jvm") version "1.3.61" //支持编译kotlin代码
}
application{
mainClassName="Main" //Main是执行的class入口
}
dependencies{
//添加kotlin的标准库
compile(kotlin("stdlib"))
}
repositories{
jcenter()
}
7.如何发布工程
双击工程右侧 distZip如下图
发布工程1.PNG
运行完成后会在工程的build目录下生成发布包，如下图
发布工程2.PNG
8.gradle中的task
在build.gradle.kts中输入以下代码
task("hello",{
println("hello i am gradle task")
})
刷新后在右侧tasks中会看到一个名为 hello的任务
任务.PNG
9.任务的依赖
在build.gradle.kts中有以下任务
task("opendoor",{
})
task("putelephant",{
}).dependsOn("opendoor")
task("closedoor",{
}).dependsOn("putelephant")
putelephant任务依赖于(dependsOn)opendoor任务，当双击运行
putelephant任务时会执行
> Task :opendoor UP-TO-DATE
> Task :putelephant UP-TO-DATE
双击closedoor任务则执行，反映的都是任务的依赖
> Task :opendoor UP-TO-DATE
> Task :putelephant UP-TO-DATE
> Task :closedoor UP-TO-DATE
10.任务task的生命周期
任务有扫描和执行两个状态
任务默认在扫描的时候会按照顺序执行一下，如果想使得任务在扫描的时候不执行
而是在真正执行的时候才执行需要通过doFirst包裹代码
task("opendoor",{
var name="hello"; //扫描时执行
doFirst{//运行时执行的
println("1开冰箱");
}
// doLast{} //运行时执行的
})
task("putelephant",{
doFirst{
println("2放入大象到冰箱");
}
}).dependsOn("opendoor")
task("closedoor",{
doFirst{
println("3关冰箱门");
}
}).dependsOn("putelephant")
11.task的任务集
任务集采用tasks关键字，里面可以定义多个任务
tasks{
"opendoor" {
}
"putelephant" {
}.dependsOn("opendoor")
"closedoor" {
}.dependsOn("putelephant")
}
12.Gradle的默认任务和默认配置
配置文件中没有配置任务任务时
在命令窗口执行
$ gradle tasks
可以查看默认的任务
Build Setup tasks
-----------------
init - Initializes a new Gradle build.
wrapper - Generates Gradle wrapper files.
Help tasks
----------
buildEnvironment - Displays all buildscript dependencies declared in root project 'Desktop'.
components - Displays the components produced by root project 'Desktop'. [incubating]
dependencies - Displays all dependencies declared in root project 'Desktop'.
dependencyInsight - Displays the insight into a specific dependency in root project 'Desktop'.
dependentComponents - Displays the dependent components of components in root project 'Desktop'. [incubating]
help - Displays a help message.
model - Displays the configuration model of root project 'Desktop'. [incubating]
outgoingVariants - Displays the outgoing variants of root project 'Desktop'.
projects - Displays the sub-projects of root project 'Desktop'.
properties - Displays the properties of root project 'Desktop'.
tasks - Displays the tasks runnable from root project 'Desktop'.
To see all tasks and more detail, run gradle tasks --all
To see more detail about a task, run gradle help --task <task>
新建任务打印工程的默认配置，刷新执行
task("print project",{
project.properties.forEach { t, any ->
println("$t : $any")
}
})
结果如下

CONFIGURE SUCCESSFUL in 162ms
配置默认执行任务，当在命令窗口中执行gradle时，默认执行名为print的任务
defaultTasks("print")
13.Gradle增量式更新
例子如下
inputs 是输入
outputs 是输出
例子是统计目录下的文件，当src下的文件没有变化时，不会重新编译
当src下的文件有更新时，再次执行会重新编译
plugins {
java
}
task("getsrcname",{
inputs.dir("src") //输入
outputs.files("info.txt") //输出
doFirst{
var srcdir=fileTree("src")
var infotxt = file("info.txt")
infotxt.writeText("");
srcdir.forEach{
if(it.isFile){
Thread.sleep(1000)
infotxt.appendText(it.absolutePath);
infotxt.appendText("\r\n");
}
}
}
})
