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:Usersherion>gradle -v------------------------------------------------------------Gradle 6.6.1------------------------------------------------------------Build time: 2020-08-25 16:29:12 UTCRevision: f2d1fb54a951d8b11d25748e4711bec8d128d7e3Kotlin: 1.3.72Groovy: 2.5.12Ant: Apache Ant(TM) version 1.10.8 compiled on May 10 2020JVM: 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) } }

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>:tasksFor example, try running gradle :gradle-common:tasksDeprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.Use ’--warning-mode all’ to show the individual deprecation warnings.See https://docs.gradle.org/6.6.1/userguide/command_line_interface.html#sec:command_line_warningsBUILD SUCCESSFUL in 4s1 actionable task: 1 executed

编译项目
