Issue using the junit plugin on osx

[remi-debette]

Hi
First, thank you for the great tool which allows to test our pipelines on local.

Running the tool installed from brew on osx, I encountered an issue that seems to be linked with the peculiar status of the platform.

When running the sample pipeline of the plugin: junit-annotate, I see the following error happening:

 bk local run .buildkite/pipeline.integration_tests.yml
(...)

--- :junit: Processing the junits
docker: Error response from daemon: Mounts denied:

is not shared from OS X and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> File Sharing.
See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info.

Apparently, when trying to mount such a folder on a mac, one would need to prefix /var with /private and use instead /private/var according to this comment

Is this a problem of the plugin or of the bk local agent?
