Description

Parent POM snippet:

<ciManagement>
  <system>parent-ci</system>
  <url>http://parent.url/ci</url>
  <notifiers>
    <notifier>
      <type>irc</type>
      <sendOnError>true</sendOnError>
      <sendOnFailure>true</sendOnFailure>
      <sendOnSuccess>false</sendOnSuccess>
      <sendOnWarning>false</sendOnWarning>
      <configuration>
        <address>irc://parent.url/#ci</address>
      </configuration>
    </notifier>
  </notifiers>
</ciManagement>

Child POM snippet:

<ciManagement>
  <system>child-ci</system>
  <url>http://child.url/ci</url>
</ciManagement>

Effective child POM:

<ciManagement>
  <system>child-ci</system>
  <url>http://child.url/ci</url>
  <notifiers>
    <notifier>
      <type>irc</type>
      <sendOnError>true</sendOnError>
      <sendOnFailure>true</sendOnFailure>
      <sendOnSuccess>false</sendOnSuccess>
      <sendOnWarning>false</sendOnWarning>
      <configuration>
        <address>irc://parent.url/#ci</address>
      </configuration>
    </notifier>
  </notifiers>
</ciManagement>

i.e. the notifiers are erroneously inherited although the child has specified its own CI management. Happens to a couple of other elements like <distributionManagement>, too. It appears the all-or-nothing style inheritance present in Maven 2.x for certain elements is not properly emulated on trunk.
