[jira] (MPMD-168) Skip report generation if results are empty

["Andreas Dangel (JIRA)" <ji...@codehaus.org>]

    [ https://jira.codehaus.org/browse/MPMD-168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=324682#comment-324682 ] 

Andreas Dangel commented on MPMD-168:
-------------------------------------

Pull request: https://github.com/apache/maven-plugins/pull/11

Please note, that the new parameter is called "skipEmptyReport" and it is by default *not true* to be backwards compatible.
However, thinking over, I guess it's not a big deal to change the behaviour here and it seems to be a better default conventional
configuration.

> Most report plugin simply skip report generation if there is nothing to display. This plugin should do the same. A parameter like {{skipIfEmpty}} should be added with default value {{true}}. The evaluation should happen in the {{canGenerate}} method.
