The Embedder does not work when started from a groovy script that is started
from maven 2
-----------------------------------------------------------------------------------------
Key: MNG-2515
URL: http://jira.codehaus.org/browse/MNG-2515
Project: Maven 2
Issue Type: Bug
Components: Embedding
Affects Versions: 2.1
Environment: Windows XP, JDK 1.5, Maven 2.0.4
Reporter: Christian Domsch
Attachments: embedder-it-test.zip
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,
Christian.
