Subject [jira] (MSITE-695) java.lang.NullPointerException in org.apache.maven.plugins.site.SiteStageDeployMojo.getTopMostParentWithSameStagingSiteURL
Date Fri, 02 Aug 2013 10:35:52 GMT

    [ https://jira.codehaus.org/browse/MSITE-695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=329985#comment-329985
] 

Herve Boutemy commented on MSITE-695:
-------------------------------------

please have a look at https://issues.apache.org/jira/browse/LOG4J2-333 too: having source
directories not matching artifact ids is against Maven conventions and will cause you extra
efforts to maintain your site

and seen from my side, you'll talk about Maven site plugin being broken when it is not: it
requires these conventions to work "magically" as you're expecting :)
