Add support for io.spring.dependency-management

[mercer]

When i use io.spring.dependency-management plugin to manage my dependencies, updateOfflineRepository will fail to resolve dependency versions, or spring-platform.

Steps to reproduce:

• apply plugin: 'io.spring.dependency-management'
• add mavenBom 'io.spring.platform:platform-bom:Brussels-SR6' to imports in dependencyManagement

Plugin 'org.springframework.boot': registration of listener on 'Gradle.buildFinished' is unsupported

     Searched in the following locations:
       - file:/root/.m2/repository/org/springframework/boot/spring-boot-dependencies/2.3.9.RELEASE/spring-boot-dependencies-2.3.9.RELEASE.pom
     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.
