Gradle 5: BOM dependencies are not written to pom file - gradle

Question

I'm trying to use a BOM to build project A with Gradle 5. The pom file that's created does not correctly contain the BOM or the dependencies coming from it (see below). Moreover, Trying to build project B that depends on A fails on project A's pom.
When working with DependencyManagementPlugin (i.e. Not using Gradle 5 native support), everything works:
apply plugin:
io.spring.gradle.dependencymanagement.DependencyManagementPlugin
dependencyManagement {
imports {
mavenBom 'myGroup:infra-bom:1.0.+'
}
}
Creates this in project A's pom in a dependencyManagement block:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>myGroup</groupId>
<artifactId>infra-bom</artifactId>
<version>1.0.25</version>
<scope>import</scope>
<type>pom</type>
</dependency>
</dependencies>
</dependencyManagement>
Trying to make it work with Gradle 5 isn't so lucky:
dependencies {
compile platform ('myGroup:infra-bom:1.0.+')
...
...
}
gradle dependencies shows correct versions from the BOM, but it creates this in project A's pom in the existing dependencies block:
<dependency>
<groupId>myGroup</groupId>
<artifactId>infra-bom</artifactId>
<version>null</version> // note the null here
<scope>compile</scope>
</dependency>
Which fails builds trying to use it.
Am I correctly using Gradle 5 native support for BOM? What does it include?
