> `ClassNotFoundException` in `@PreDestroy` method when Maven extension
> declared in `pom.xml`
> -------------------------------------------------------------------------------------------
>
> Key: MNG-8217
> URL: https://issues.apache.org/jira/browse/MNG-8217
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.9.8
> Reporter: Cyrille Le Clerc
> Priority: Major
> Fix For: 4.0.0-rc-2
>
>
> The `{{{}@PreDestroy{}}}` method of JSR 330 based Maven extensions fail with
> a `{{{}ClassNotFoundException{}}}` when the extension is declared through the
> `{{{}<build><extensions>...</extensions></build>{}}}`.
> The problem doesn't happen when the Maven extension is declared through the
> `{{{}.mvn/extensions.xml{}}}` file or `{{{}mvn
> -Dmaven.ext.class.path=...{}}}` command line arg.
> This suggest the classes of the extension are unloaded too early, before
> `{{{}@PreDestroy{}}}` is invoked, when when the extension is declared through
> the `{{{}<build><extensions>...</extensions></build>{}}}`.
> Test case:
