Gradle + Nexus 管理Spring Boot的Jar

前言

Spring Boot 使你能轻松地创建独立的、生产级的、基于 Spring 且能直接运行的应用程序。
Gradle 是一种构建工具，和已有的ant、maven相比Gradle更简洁高效，胜任复杂的构建任务，社区活跃，技术成熟。

Spring Boot的gradle插件

Spring Boot Gradle插件在Gradle中提供Spring Boot支持，你可以用它来做打包（生成可执行jar或war），运行Spring Boot应用程序，并提供的依赖关系管理spring-boot-dependencies。
Spring Boot的Gradle插件需要Gradle 4.0或更高版本。

dependencies {
         classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }

引用第三方jar

Nexus作为Gradle的私服，请参考https://www.jianshu.com/p/f50fd2531db1

打包

gradle 默认有bootJar任务
需要jar包时执行bootJar命令即可。

上传开发版本运行 devUpload 命令，上传发布版本运行releaseUpload命令。
