Description

Parent POM snippet:

<extensions>
  <extension>
    <groupId>org.apache.maven.wagon</groupId>
    <artifactId>wagon-webdav</artifactId>
    <version>1.0-beta-1</version>
  </extension>
</extensions>

Child POM snippet:

<extensions>
  <extension>
    <groupId>org.apache.maven.wagon</groupId>
    <artifactId>wagon-webdav</artifactId>
    <version>1.0-beta-2</version>
  </extension>
</extensions>

Effective child POM:

<extensions>
  <extension>
    <groupId>org.apache.maven.wagon</groupId>
    <artifactId>wagon-webdav</artifactId>
    <version>1.0-beta-2</version>
  </extension>
  <extension>
    <groupId>org.apache.maven.wagon</groupId>
    <artifactId>wagon-webdav</artifactId>
    <version>1.0-beta-1</version>
  </extension>
</extensions>

i.e. there is no conflict resolution and both versions of the extension are loaded.
