Maven local repository location for Linux and Windows

You don't do that in the POM, but in your ~/.m2/settings.xml, which would be different for both Linux and Windows, so no problem. See the localRepository element:

<settings>
    <localRepository>d:\repository</localRepository>
    <!-- or -->
    <localRepository>/media/234242342/repository</localRepository>
    ...
 </settings>

Each OS needs an M2_HOME as per the Maven documentation. Inside $M2_HOME/conf/ you can put a settings.xml file and in that you can specify the location for the local repository using the <localRepository/> element.

So for your specific system, in Windows use

<localRepository>d:\repository</localRepository>

and in Linux

<localRepository>/media/234242342/repository</localRepository>
