[jira] Commented: (MNG-4464) Improve handling of relative paths with backslashes

["Anders Kr. Andersen (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-4464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=201382#action_201382 ] 

Anders Kr. Andersen commented on MNG-4464:
------------------------------------------

In my eyes writing <relativePath>..\pom.xml</relativePath> means <<dot>> <<dot>> <<escapeP>> <<letter o>> <<letter m>> etc.
And it makes no sense.
a correct way must be to write <relativePath>../pom.xml</relativePath>

I have written <relativePath>../pom.xml</relativePath> several places, and it seems to work. 

So yes backslash is an error. And should procduce a warning.
The question is just how do we know that escape is used wrong?
A sentence like <relativePath>\<SYSTEM\$HOME\>pom.xml</relativePath> could make sense on Open VMS.

My conclusion is that this is just something that developers should know.

A simulary situation is to write <relativePath>${myParameter}/pom.xml</relativePath> and not having set a value to property myParameter. In this case maven tells that it cannot find file ${myParameter}/pom.xml.

Maybe maven's pom checkker tool could be told to check for these things?

>             Project: Maven 2
>          Issue Type: Improvement
>          Components: POM
>    Affects Versions: 2.2.1, 3.0-alpha-4
>         Environment: Unix, Mac
>            Reporter: Benjamin Bentmann
>            Priority: Minor
>
> Consider this snippet:
> {code:xml}
> <parent>
>   <relativePath>..\pom.xml</relativePath>
> </parent>
> {code}
> Note in particular the backslash used in the path. While this path will be properly resolved on a Windows box, it will fail to resolve the local parent on a Unix/Mac box (as the backslash is not a separator but escape character here). This applies to other paths in the POM as well.
> For platform-independent behavior, we should either encourage the user to use forward slashes (by means of validation warnings/errors) or have Maven convert the paths internally.
