Should you use the parent if you are using the spring platform bom?

Some dependency versions are not in so I've added the spring platform BOM, is the parent declaration still useful?

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.1.RELEASE</version>
</parent>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>1.1.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

I personally prefer to use platform-bom as a parent, i.e.

<parent>
    <groupId>io.spring.platform</groupId>
    <artifactId>platform-bom</artifactId>
    <version>1.1.1.RELEASE</version>
    <relativePath />
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

In this way I don't have to define spring-boot version number and it is automatically updated with newer version of spring platform and I don't have to worry about any inconsistencies.

See http://docs.spring.io/platform/docs/1.1.1.RELEASE/reference/htmlsingle/#appendix-dependency-versions for complete list of all managed dependencies.

EDIT: As pointed out by Andy Wilkinson, spring platform inherits spring-boot-starter-parent so all "sensible defaults" as described in http://docs.spring.io/spring-boot/docs/1.2.1.RELEASE/reference/htmlsingle/#using-boot-maven apply as well.

There is a important difference between importing a BOM (in the dependencyManagement section) and using a parent

The BOM imported in dependencyManagement only provides defaults for dependencies, but a Parent-way include the other sections too (plugins, plugin-managent, dependencies, dependencyManagement...)

So when you remove the parent spring-boot-starter-parent then you have to copy the the plugin-managent stuff you need first.
