> [regression] Custom packagings from build extensions are not reliably loaded
> during a reactor build

> Key: MNG-4357
> URL: http://jira.codehaus.org/browse/MNG-4357
> Project: Maven 2
> Issue Type: Bug
> Components: Plugins and Lifecycle, Reactor and workspace
> Affects Versions: 3.0-alpha-3
> Reporter: Benjamin Bentmann

> Building XWiki platform with trunk in one go produces
> {noformat}
> [ERROR] Unknown packaging: maven-archetype @
> org.xwiki.platform.tools:xwiki-archetype-macro:1.1-SNAPSHOT
> {noformat}
> The mentioned project properly declares the required build extensions in its
> POM and builds fine in isolation.
> The issue boils down to the active component map
> {{DefaultLifecycleExecutor.lifecycleMappings}} not being properly updated
> when switching the projects in the reactor. In detail,
> {{AbstractComponentCollection.checkUpdate()}} from Plexus doesn't update the
> map if the number of component descriptors hasn't changed. This apparently
> misses the situation where the total count of component descriptors from two
> different class realms is the same but the set of role hints has changed,
> e.g. {{[one, two]}} vs. {{[one, three]}}.
