Spring Cloud Release Train is a curated set of dependencies across a range of Spring Cloud projects. You consume it by using the spring-cloud-dependencies POM to manage dependencies in Maven or Gradle. The release trains have names, not versions, to avoid confusion with the sub-projects. The names are an alphabetic sequence (so you can sort them chronologically) with names of London Tube stations ("Angel" is the first release, "Brixton" is the second).

Using Spring Cloud Dependencies with Spring IO Platform

The Spring IO Platform is a modular, enterprise-grade curated set of dependencies. To use the Spring Cloud Starters with Spring IO Platform, you must import the Spring Cloud Dependencies bill of materials (BOM) first.

To use version Cairo-SR3 of the Spring IO Platform and Spring Cloud Release Train Greenwich.BUILD-SNAPSHOT with Maven, update the pom.xml as follows:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Greenwich.BUILD-SNAPSHOT</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>Cairo-SR3</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
The Spring Cloud Dependencies BOM must go first, so that its dependencies have precedence of the Spring IO Platform dependencies.

For gradle, update the build.gradle as follows:

buildscript {
	repositories {
		mavenCentral()
	}
	dependencies {
		classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.0.M1")
	}
}

apply plugin: 'spring-boot'

dependencyManagement {
	imports {
		mavenBom "org.springframework.cloud:spring-cloud-dependencies:Greenwich.BUILD-SNAPSHOT"
		mavenBom 'io.spring.platform:platform-bom:Cairo-SR3'
	}
}
