[jira] Closed: (MNG-2515) The Embedder does not work when started
from a groovy script that is started from maven 2
[ http://jira.codehaus.org/browse/MNG-2515?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Brett Porter closed MNG-2515.
-----------------------------
Assignee: Brett Porter
Resolution: Won't Fix
Fix Version/s: (was: Reviewed Pending Version Assignment)
I expect only running the embedder for the current version of Maven, once available, will work unless you fork which can probably be handled separately

> Affects Versions: 2.0-alpha-1
> Environment: Windows XP, JDK 1.5, Maven 2.0.4

> The deploymentserver:changestage plugin starts a groovy script that again starts a maven 2.1-SNAPSHOT embedder. This fails due to classloading issues because the classloader for the groovy script contains a thread context classloader a s a parent. This parent classloader contains all classes from the maven 2.0.4 process that started the plugin. The embedder now fails to start because the parent classloader contains conflicting classes from 2.0.4 while the embedder is 2.1-SNAPSHOT.
> The test case in the zip contains the source for the deploymentserver-mojo and the projects that this mojo should operate on. To start the test, install the mojo, and start maven in the productA project with "mvn deploymentserver:changestage". For this to work the settings.xml must contain
> <pluginGroups>
> <pluginGroup>innowake.lifecycle.deployment.engine.plugin</pluginGroup>
> </pluginGroups>
> The zip also contains the groovy jars to be copied in the local repository.
> Greetings,
