site:stage-deploy fails on Windows for projects with 3 levels of modules

My case involves deploying a staging site for doxia-1.0. The project structure is like this:

doxia
  |
  `-- doxia-modules
            |
            `-- doxia-module-confluence

After running 'mvn site:stage-deploy -Preporting' I get the following error message:

Executing command: scp -t "/www/maven.apache.org/doxia/doxia-1.0.x/staging/doxia-modules\doxia-module-confluence/./wagon7568.zip"
Transfer error: java.io.IOException: SCP terminated with error: 'scp: /www/maven.apache.org/doxia/doxia-1.0.x/staging/doxia-modules\doxia-module-confluence/./wagon7568.zip: No such file or directory'
Transfer error: org.apache.maven.wagon.TransferFailedException: Error occured while deploying './wagon7568.zip' to remote repository: scp://people.apache.org/www/maven.apache.org/doxia/doxia-1.0.x/staging/doxia-modules\doxia-module-confluence: SCP terminated with error: 'scp: /www/maven.apache.org/doxia/doxia-1.0.x/staging/doxia-modules\doxia-module-confluence/./wagon7568.zip: No such file or directory'

If you look closely at the scp: URL it contains a '\' instead of a '/' between doxia-modules and doxia-module-confluence.
