Mounting the DEV@cloud Private WebDav Repository fails

Question

I'm using the private repository to store my own custom settings.xml. When i try to use it i get the following log message:

$ /usr/bin/tenant-isolate sudo /opt/jenkins/sbin/mount-webdav https://repository-laures.forge.cloudbees.com/private laures alert
mountpoint: /private/laures: No such file or directory

when my buildjob later wants to access my custom settings.xml i get an exception:

Executing Maven:  -B -f /scratch/jenkins/workspace/JacksonLegacyIntrospector/pom.xml -gs /private/laures/settings.xml clean verify site emma:emma

I was following the cloudbees guide: https://developer.cloudbees.com/bin/view/DEV/Sharing+Files+with+Build+Executors

Did i do something wrong?

This job is validating pull-requests. A malicious user could hack your build script in a pull request and extract confidential informations from your account.

To prevent this, CloudBees run such a build using tenant-isolate script. This prevent /private to get mounted, this is intentional - but not nicely reported on the web UI.
