Subject [jira] Commented: (FOR-993) Plugins not finding the optional plugin specific Locationmap causes Errors instead of warnings.
Date Fri, 20 Nov 2009 00:28:39 GMT

    [ https://issues.apache.org/jira/browse/FOR-993?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12780346#action_12780346
] 

Tim Williams commented on FOR-993:
----------------------------------

If I understand this issue correct - and I'm not at all sure I do - then we're in a bit of
a catch-22.  We can't know currently if the mount is intentional and the user would actually
want it to fail or if it's more casual, as in "yeah, mount it if it's there".  For that we
could add an attribute to the mount node of the locationmap grammar (e.g. <mount required="false"
src="..."/>) 

The other option, forcing all projects to have one, doesn't seem very considerate to me. 


Ross, Gavin, would the new attribute suffice?  It'd be enough to let us know in the LM whether
to error or print a debug statement.  
Thanks,

> Whilst checking error logs for another issue, I spotted that the locationmap was not
being found.
> So I tried it in serveral plugins, all with the same result, the locationmap is not being
found.
> The locationmap is normally found in %PROJECT_HOME%/src/documentation/content/ directory
> Our own site docs it can be found in site-author/content.
> However for Plugins all the locationmap.xml files are located in %pluginHome%/ root directory.
> The locationmap.xml file for plugins is not being looked for in root but in the content
directory.
