Description

The OBR plugin uses a remote 'lock-file' to lock the remote OBR while it is being updated.
To lock the OBR, it uploads a file containing "LOCKED", to unlock it uploads an empty file.

For some reason with certain transports (such as file:) uploading an empty file does not
overwrite the existing file, which means the remote OBR will remain locked.

To workaround this issue we should upload a file containing a single space, and change
the lock check to trigger on files that are more than 2 bytes long. (this is simpler than
finding the root cause in maven or wagon and waiting for a fix)
