deploy:deploy-file via wagon-webdav delete pom file referenced by -DpomFile

I try to upload to a remote repository a 3rd party jar for which I have written a custom pom. I use this command:

mvn deploy:deploy-file -Dfile=toolkit-0.24.jar -DpomFile=toolkit-0.24.pom -DrepositoryId=sourcesense -Durl=dav:https://dev.sourcesense.com/repos/dev/maven2 -e

The jar is uploaded correctly and metadata xml files created as they should. But the pom of the project (toolkit-0.24-pom) is not uploaded becouse maven cannot find it! Indeed, pom is deleted from my disk during maven goal executions.

I have followed this instructions: http://docs.codehaus.org/display/MAVENUSER/Deploying+3rd+Party+Jars+With+WebDAV
so I have my pom.xml that points to wagon-webdav and the toolkit-0.24 pom, which I have written, is a simple pom with one dependency that works on my local repo

Take a look at the log, I am wondering of what
[INFO] Retrieving previous metadata from sourcesense
means. I attach the toolkit-0.24.pom

+ Error stacktraces are turned on.
