使用 Kotlin , Groovy ，Java 开发一个自己的 Gradle 插件
先上效果图：

功能说明：
korGenerate:
自动生成 Entity，Dao，Controller 模板代码
korFront:
自动 copy 前端 front 工程目录下面的 —— nowa 构建的 dist 目录下的静态资源文件：html, css, js

build.gradle
group 'com.easykotlin.plugin'
version '1.0-SNAPSHOT'
buildscript {
ext.kotlin_version = '1.2.0'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'groovy'
apply plugin: 'java'
apply plugin: 'kotlin'
apply plugin: 'maven'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
compile 'org.codehaus.groovy:groovy-all:2.3.11'
testCompile group: 'junit', name: 'junit', version: '4.12'
compile gradleApi()
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
kotlinOptions.jvmTarget = "1.8"
}

其中，compile gradleApi() 是使用 Gradle 的 API 依赖。
配置上传到 maven 仓库，这里我们配置上传至本机的目录下：
apply plugin: 'maven'
uploadArchives {
repositories {
mavenDeployer {
repository(url: uri('/Users/jack/.m2/repository'))
}
}
}
点击右侧工具栏的： upload > uploadArchives

执行日志：

新建Gradle 插件的执行逻辑的实现类

实现代码编写：

package com.easykotlin.kor
import org.gradle.api.Plugin
import org.gradle.api.Project
class KorPlugin implements Plugin{
@Override
void apply(Project project) {
}
}
具体实现代码：
package com.easykotlin.kor
import org.gradle.api.Plugin
import org.gradle.api.Project
class KorPlugin implements Plugin {
@Override
void apply(Project project) {
project.task("kor") << {
println("Hello, Kor !")
println(project.group.toString())
println(project.artifacts.toString())
}
project.task("nowabuild") << {
NowaBuildJava nb = new NowaBuildJava()
String projectDir = project.projectDir.absolutePath
println("projectDir = $projectDir")
nb.nowaBuild(projectDir)
}
}
}

build.gradle
group 'com.easykotlin.plugin'
version '1.0-SNAPSHOT'
buildscript {
ext.kotlin_version = '1.2.0'
repositories {
mavenCentral()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: 'groovy'
apply plugin: 'java'
apply plugin: 'kotlin'
apply plugin: 'maven'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
// compile 'org.codehaus.groovy:groovy-all:2.4.11'
testCompile group: 'junit', name: 'junit', version: '4.12'
compile gradleApi()
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
kotlinOptions.jvmTarget = "1.8"
}
uploadArchives {
repositories {
mavenDeployer {
repository(url: uri('/Users/jack/.m2/repository'))
}
}
}

然后，我们在另外项目 reakt 中使用刚才开发的插件：
build.gradle
buildscript {
ext {
kotlinVersion = '1.2.0'
springBootVersion = '2.0.0.M7'
}
repositories {
mavenLocal()
mavenCentral()
maven { url "https://repo.spring.io/snapshot" }
maven { url "https://repo.spring.io/milestone" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}")
classpath("org.jetbrains.kotlin:kotlin-allopen:${kotlinVersion}")
classpath('com.easykotlin.plugin:kor:1.0-SNAPSHOT')
}
}
apply plugin: 'com.easykotlin.kor'
