Gradle基础笔记

配置镜像

修改 gradle>wrapper>gradle-wrapper.properties

distributionUrl=https\://mirrors.aliyun.com/macports/distfiles/gradle/gradle-8.6-all.zip

配置父项目

使用 subprojects

编码问题处理

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

依赖版本控制

增加使用插件

apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

子项目排除依赖

使用configuration

    configurations {
        all*.exclude group: 'javax.servlet'
    }

项目之间依赖

使用compile关键字，不过目前Gradle版本对于compile不再支持了，可以使用api关键字或implementation关键字

    dependencies {
        implementation project(':sb-common')
    }

完整示例

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://repo.spring.io/libs-milestone' }
    }
    dependencies {
        classpath 'org.springframework.boot:spring-boot-gradle-plugin:3.2.2'
    }
}
