[jira] [Commented] (MPIR-378) NPE during site generation when
module packaging is 'bundle'
[ https://issues.apache.org/jira/browse/MPIR-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16812944#comment-16812944 ]
Gabriel Belingueres commented on MPIR-378:
------------------------------------------
Hi Alexey:
When running your example project (non recursive), it fails regardless of the module's packaging (tested with bundle, jar, pom), so my best guess is something related to the presence of the maven-bundle-plugin. Did you ask/report the issue in the felix project?
We could easily check for MavenExecutionRequest.isRecursive() flag on modules report to avoid the NPE but first I'd like to understand where the issue come from.
