Cyrille Le Clerc updated MNG-8217:
----------------------------------
Summary: `ClassNotFoundException` in `@PreDestroy` method when Maven
extension declared in `pom.xml` (was: `{{ClassNotFoundException}}` in
`{{@PreDestroy}}` method when Maven extension declared in `{{pom.xml}}`)
> `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
>
> 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:
> *
