[matthewpwilson]

Describe the bug
When running Appsody on OpenShift and setting APPSODY_K8S_EXPERIMENTAL, an error occurs during appsody init while creating /.m2.

To Reproduce
Steps to reproduce the behavior:

1. Create an image containing Buildah and Appsody.
2. Deploy it on OpenShift.
3. Set APPSODY_K8S_EXPERIMENTAL=TRUE
4. Run appsody init experimental/vertx.

Expected behavior
Init succeeds without warnings.

Actual behaviour
The following warning occurs:
