[jira] Commented: (FELIX-2487) Failed to compile iPOJO 1.6.0
project with NPE (related to annotation computation)
[ https://issues.apache.org/jira/browse/FELIX-2487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12893539#action_12893539 ]
Guillaume Sauthier commented on FELIX-2487:
-------------------------------------------
Do you describe your component using XML *and* annotations ? I mean a part in the metadata.xml and some annotations in the code ?
If so, you have to choose where you describe your component: either in the metadata.xml or using annotations, but not both.
The iPOJO manipulation process does not merge XML metadata and annotations for a given component type.
In any case, I agree that the NPE is not really nice ;)
