 = Spring Data - Release Train BOM example
 
-This project shows the usage of the Spring Data release train in a non-Spring-Boot project. It basically consists of the `pom.xml` with the following noteworthy sections:

+In both Maven and Gradle a couple of properties are used to define the versions of Spring Framework and Spring Data to use. For Spring Framework a plain version is used.

+
+== Gradle
+
+Gradle does not support Maven BOMs out of the box so the first thing to do is to declare a buildscript dependency on the https://github.com/spring-gradle-plugins/dependency-management-plugin[dependency management plugin] and apply it to the project.
+
+With the plugin applied, the `dependencyManagement` section can be used to import the Spring Framework and Spring Data BOMs.
