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-vintage-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 * 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)
}
}

验证

Gradle 查看所有项目

gradle projects
> Task :projects
------------------------------------------------------------
Root project
------------------------------------------------------------
Root project 'gradle-parent'
+--- Project ':gradle-common'
+--- Project ':gradle-demo'
\--- Project ':gradle-demo2'

To see a list of the tasks of a project, run gradle <project-path>:tasks
For example, try running gradle :gradle-common:tasks
