Gradle里面兩個 依賴管理插件，可以不用關心 具體jar版本號

Using the plugin with Spring Boot

There are some similarities between this plugin and Spring Boot’s Gradle plugin. For example, the Spring Boot plugin also allows dependencies to be declared without a version, however it doesn’t affect transitive dependencies and doesn’t honor Maven exclusions.

In the forthcoming Spring Boot 1.3 we have removed Boot’s own dependency management and started using the dependency management plugin instead. For users of earlier versions of Spring Boot, the two plugins will happily co-exist and you can configure the dependency management plugin to use Spring Boot’s starter bom:

 

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath "io.spring.gradle:dependency-management-plugin:0.5.1.RELEASE"
    classpath "org.springframework.boot:spring-boot-gradle-plugin:1.2.3.RELEASE"
  }
}

apply plugin: "io.spring.dependency-management"
apply plugin: "spring-boot"

repositories {
  jcenter()
}

dependencyManagement {
  imports {
    mavenBom 'org.springframework.boot:spring-boot-starter-parent:1.2.1.RELEASE'
  }
}

dependencies {
  compile "org.springframework.boot:spring-boot-starter-web"
}
