maven-metadata-<repository>.xml not generated when deploying to repository via scpexe protocol

Further to the below, if I deploy a project to the remote repository
successfully via NFS and then switch over to scpexe, subsequent
deployments over scpexe work as expected.

This appears to be due to the presence of the maven-metadata.xml files
in the repository. If I remove these the deployment breaks again.

The root problem appears to be with the deployment and/or generation of
the metadata when using scpexe.

When broken, the root exception in the stack trace is:

Caused by: java.io.FileNotFoundException:
/home/amm/.m2/repository/com/distra/useful/useful/maven-metadata-distra.xml.tmp
(No such file or directory)

Checking my local repository reveals that the maven-metadata-distra.xml
has not been generated. maven-metadata-local.xml is still generated.

maven-metadata-distra.xml IS generated when deploying via NFS.

So, in a nutshell, maven-metadata-<repository>.xml does not appear to be
generated correctly when using the scpexe protocol.

Would anyone care to confirm this before I raise a bug?

I have tested with the normal scp protocol and deployment works as
expected. Using scp however I have to hard-code my key's password in
settings.xml. This is what I am trying to get around by using scpexe.

Thanks,
