title: Why is spring-boot-dependencies in dependencyManagement?
body: <p>The Spring documentation <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-build-systems.html" rel="nofollow noreferrer">Using Spring Boot without the parent POM</a> shows that the dependency on <code>spring-boot-dependencies</code> is added to the <code>dependencyManagement</code> section. Is this really correct?</p>
  
  <p>spring-boot-dependencies specifies version properties for all the dependencies. However, these properties are not available in the POM that uses <code>spring-boot-dependencies</code>. Presumably, this is because <code>spring-boot-dependencies</code> is in <code>dependencyManagement</code>.</p>
  
  <p>spring-boot-dependencies only includes <code>dependencyManagement</code> and <code>pluginManagement</code>. So it seems possible to include <code>spring-boot-dependencies</code> as a dependency (not dependencyManagement) without adding unnecessary dependencies.</p>
  
  <p>So why is <code>spring-boot-dependencies</code> to be included as <code>dependencyManagement</code>?</p>
