IDEA 2020.2 +Gradle 6.6.1 + Spring Boot 2.3.4 创建多模块项目的超详细教程

环境介绍 IDEA

我用的是2020.2

Gradle

安装参考 Gradle安装配置

我这安装的是6.6.1

C:\Users\herion>gradle -v

------------------------------------------------------------

Gradle 6.6.1

------------------------------------------------------------

Build time: 2020-08-25 16:29:12 UTC

Revision: f2d1fb54a951d8b11d25748e4711bec8d128d7e3

Kotlin: 1.3.72

Groovy: 2.5.12

Ant: Apache Ant(TM) version 1.10.8 compiled on May 10 2020

JVM: 1.8.0_211 (Oracle Corporation 25.211-b12)

OS: Windows 10 10.0 amd64

创建 gradle-parent New Project --> Spring Initalizr 选择jdk版本，我这里使用1.8

Next

–> 根据需求修改 Group、Artifact、version 、Type、name、package 等，选择所需依赖创建项目

创建成功后删除src 目录

创建子模块 gradle-demo

选中gradle-parent–> new -->Module

创建子模块操作与创建gradle-parent 雷同，这里就不做复述了，创建好gradle-demo后在gradle-parent的settings.gradle 中引入模块依赖 include ‘gradle-demo'

删除gradle-demo 中settings.gradle文件，否则不能喝gradle-parent建立依赖关系

定义gradle 自身所需资源

buildscript {

ext {

springBootVersion = '2.3.4.RELEASE'

springBootManagementVersion = '1.0.8.RELEASE'

springCloudVersion = 'Hoxton.SR6'

REPOSITORY_HOME = "http://maven.aliyun.com"

}

repositories {

maven { url '${REPOSITORY_HOME}/nexus/content/groups/public/' }

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("io.spring.gradle:dependency-management-plugin:${springBootManagementVersion}")

}

}

修改gradle-parent项目build.gradle 配置全项目通用配置

allprojects {

apply plugin: 'java'

apply plugin: 'idea'

group = 'com.herion'

sourceCompatibility = JavaVersion.VERSION_1_8

targetCompatibility = JavaVersion.VERSION_1_8

}

子项目通用配置

subprojects {

apply plugin: 'org.springframework.boot'

apply plugin: 'io.spring.dependency-management'

[compileJava, compileTestJava, javadoc]*.options*.encoding = 'UTF-8'

//仓库

repositories {

maven { url '${REPOSITORY_HOME}/nexus/content/groups/public/' }

mavenCentral()

maven { url 'https://repo.spring.io/snapshot' }

maven { url 'https://repo.spring.io/milestone' }

}

dependencies {

implementation 'org.springframework.boot:spring-boot-starter'

compileOnly 'org.projectlombok:lombok'

developmentOnly 'org.springframework.boot:spring-boot-devtools'

annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'

annotationProcessor 'org.projectlombok:lombok'

testImplementation('org.springframework.boot:spring-boot-starter-test') {

exclude group: 'org.junit.vintage', module: 'junit-vxuMUCbXchRintage-engine'

}

}

dependencyManagement {

imports { mavenBom("org.springframework.boot:spring-boot-dependencies:${springBootVersion}") }

imports { mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}" }

}

test {

useJUnitPlatform()

}

}

发布插件配置

/**

* 发布插件

*/

publishing {

publications {

mavenJava(MavenPublication) {

from components.java

versionMapping {

usage('java-api') {

fromResolutionOf('runtimeClasspath')

}

usage('java-runtime') {

fromResolutionResult()

}

}

}

}

// 发布仓库

repositories {

maven {

// TODO 换成自己的私服地址

def releasesRepoUrl = "http://my.repo.com/nexus/repository/maven-releases"

def snapshotsRepoUrl = "http://my.repo..com/nexus/repository/maven-snapshots"

url = version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl

credentials {

username nexusUser

password nexusPassword

}

}

}

}

configurations {

[apiElements, runtimeElements].each {

it.outgoing.artifacts.removeIf { it.buildDependencies.getDependencies(null).contains(jar) }

it.outgoing.artifact(bootJar)

}

}
