[jira] Commented: (MNG-3760) Support property ${baseurl} to get RFC-compliant URL of project base directory

["Lars Beuster (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-3760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=170682#action_170682 ] 

Lars Beuster commented on MNG-3760:
-----------------------------------

Maven 2.1.0: The new property (the final name seems to be ${project.baseUri}) works in the POM but isn't replaced with it's current value during resource filtering.

> If people currently need a URL to their project base directory or any file within, they need to write {{file://$\{basedir}}/}}. The problem about this approach is that it doesn't deliver a [RFC-compliant URL|http://tools.ietf.org/html/rfc3986] since characters are not properly percent-encoded. Also, the exact number of slashes between {{file:}}  and {{${basedir}}} depends on the OS (e.g. {{file:///C:/user/}} and {{file:///home/user}}, Unix paths have a leading slash by themselves, Windows not). This makes it currently impossible to configure plugins that expect a URL as input and do strict URL parsing.
> For this reason, I suggest to support an additional property {{${baseurl}}} with the value
> {code:java}
>   baseurl = new File( basedir ).toURI().toString()
> {code}
> for POM interpolation.
> Some day, when Maven/Wagon itself handle percent-encoded {{file:}} URLs correctly (WAGON-111), this property could also be used to define local deployment repos like we commonly use for testing.
