BlobStore.clearContainer()
I'm using 2.1.1 of jClouds to remove contents of a bucket using
clearContainer(container, ListContainerOptions). I'm getting a "Prefix and
delimiter support has not yet been added" Exception if there is a prefix,
although the docs seem to indicate it should work.
https://jclouds.apache.org/reference/javadoc/2.1.x/org/jclouds/blobstore/BlobStore.html#clearContainer
If that doesn't work, what is the best way to remove everything under a
prefix with jClouds?
Thanks,

Sure, I'll give it a try. Is there some way to get on the jclouds slack
channel?
Cheers,
Joe

I do not understand why DeleteAllKeysInList.execute eager throws an
exception here; DeleteAllKeysInList.getListing passes
ListContainerOptions to BlobStore.list so I believe this should just
work if you remove the check. Could you test this and report it in a
JIRA issue? Pull requests welcome, of course!
Speculating, this code was written back when jclouds only supported
pseudo-directories, a least common denominator since Atmos does not
support prefixes. Fast-forwarding to today, all providers except Atmos
support prefix and delimeter so we should not constrain them by an
abandoned API's quirks. I believe the existing implementation can be
substantially simplified.
