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

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

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)
        }
    }
