1 选择File->New->Project,选择gradle java 后 点击next

2 输入项目的GroupId和ArtifactId ,GroupId一般用域名反置表示,例如:com.ws ArtifactId:项目代号,然后点击Next

3 按如下图所示勾选,使用自动import,当gradle配置文件发生改变时,自动下载jar依赖.勾选使用本地gradle 版本,然后点击next 生成项目

4 如下图

5 生成项目后,src目录可以删掉 因为我们创建的是多module项目.下面会说gradle 多项目的配置

gradle多项目配置

在根项目目录下的build.gradle文件中添加如下配置

buildscript {ext{springBootVersion='2.1.6.RELEASE'}repositories {maven {url "http://maven.aliyun.com/nexus/content/groups/public"}}dependencies {classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")}
}group 'com.ws'
version '1.0-SNAPSHOT'allprojects {repositories {maven {url "http://maven.aliyun.com/nexus/content/groups/public"}}
}subprojects {apply plugin: 'java'// plugin用于保持spring boot依赖库的版本一致apply plugin: 'org.springframework.boot'apply plugin: 'findbugs'apply plugin: 'maven'apply plugin: "io.spring.dependency-management"compileJava.options.encoding = "UTF-8"compileTestJava.options.encoding = "UTF-8"dependencyManagement {dependencies {dependency 'ch.qos.logback:logback-classic:1.2.3'dependency 'ch.qos.logback:logback-core:1.2.3'dependency 'com.fasterxml.jackson.core:jackson-databind:2.9.9.3'dependency 'com.fasterxml.jackson.core:jackson-core:2.9.9'dependency 'com.fasterxml.jackson.core:jackson-annotations:2.9.9'dependency 'com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:2.9.9'dependency 'com.fasterxml.jackson.module:jackson-module-afterburner:2.9.9'dependency 'com.alibaba:druid:1.1.16'dependency 'com.google.guava:guava:19.0'dependency 'io.netty:netty-codec-http:4.1.8.Final'dependency 'io.netty:netty-transport-native-epoll:4.1.8.Final'dependency 'net.bytebuddy:byte-buddy-agent:1.7.9'dependency 'org.ow2.asm:asm:5.2'dependency 'org.projectlombok:lombok:1.16.18'dependency 'com.google.code.findbugs:jsr305:3.0.2'dependency 'commons-io:commons-io:2.5'dependency 'org.apache.commons:commons-exec:1.3'dependency 'org.apache.commons:commons-lang3:3.5'dependency 'org.apache.commons:commons-collections4:4.1'dependency 'io.projectreactor:reactor-core:3.2.8.RELEASE'}}findbugs {ignoreFailures=true}}

配置说明:
buildscript : gradle 构建脚本配置,可以通过ext配置变量名和值,以及配置构建脚本中需要用到的插件,以及插件的repositories,这里我们使用spring-boot-gradle-plugin插件,他会自动管理引入的spring-boot的依赖版本

subprojects : 因为是多module项目,使用subproject对module 共用的一些依赖进行管理.
dependencyManagement: 这个配置来自 io.spring.dependency-management,统一管理依赖,但是它不会引入这些依赖,当在某个module下的build.gradle中使用dependencies引入依赖的时候,才会真正的引入,在module中引入的时候 就可以不指定版本了.

创建module

一个modlue相当于一个子项目
1 选中根目录test,右键->new->module ,如下图所示

2 新建module后 得到如下图所示目录结构

3 修改module下的build.gradle配置文件 直接添加项目需要的依赖

dependencies {testCompile group: 'junit', name: 'junit', version: '4.12'// https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-webcompile group: 'org.springframework.boot', name: 'spring-boot-starter-web'// https://mvnrepository.com/artifact/org.springframework.kafka/spring-kafkacompile group: 'org.springframework.kafka', name: 'spring-kafka'}

4 这样 整个项目就都配置好了,如下图,写一个测试用例

5 生成可运行jar包
