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?

> Key: MNG-4464
> URL: http://jira.codehaus.org/browse/MNG-4464
> 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.
