Hi Torben,
Makes sense. While it isn't a full-up integration test, I was able to
build and run most of the GeoMesa unit tests with Guava 18. There was
only one slightly issue; in one module, there was a method used which is
not present in Guava 18.
I think if we removed that from GeoMesa, we'd be able to work with Guava
11-18. The GeoMesa datastore jars/zips/extensions targeting GeoServer
2.8.x do not include Guava since Guava 17 is part of the GeoServer
distribution.
Anyhow, having classloaders per extension might be necessary at some
point, but I'd like to try and help avoid it;).
Cheers,
Jim

Hi Jim
One thing we were looking at was trying to make sure that GeoMesa
(using Guava 17 by way of Accumulo) and ElasticGeo (using Guava 18 by
way of Elasticsearch) wouldn't cause conflicts if both extensions were
installed. One suggestion was to try and have each extension run in
its own class loader. However, if we want to have a different version
of Guava for these two dependencies, then we could not have Guava in
core GeoServer (else it would conflict with one of the extensions).

Hi Jody,
Thanks for the clarification; I didn't get it that the line was a
suggestion to remove Guava.
From a cursory look, it appears that GeoTools has few dependencies
on Guava. For GeoServer, it seems that GWC and other pieces want
to be able to have a Guava cache. I don't think there's a Java 8
analog for those caching options...
For my money, I'd be happy if GeoServer picked a version of Guava
(or a range of versions) to aim for. Some of the Guava
functionality has stayed the same between versions, and modules
which can leverage that might work out better together. (That is,
there'd be some utility in using more common Guava functionality
rather than a feature which is only in one version.)
Do you have more details about the dependency issues with
GeoMesa? (I do see where the ElasticGeo instructions have you
ripping out Guava, etc.)
Joda doesn't use Guava. Bringing up GeoServer and GeoMesa
dependencies made me think of the Joda updates.
Cheers,
Jim

As per meeting notes I would like to know if removing Guava is
something we can do over the course of 2.10 development.
So does Joda time use Guava as well?

Hi all,
Looks like there is plenty going on, I just wanted to add
some info re: GeoMesa and Guava.
Since GeoMesa code ends up being deployed in GeoServer,
Hadoop, and other environments, Guava is a provided
dependency. We try to use Guava features which have remained
consistent between Guava versions (ranging from 11 to 17 or so).
From talking to Tyler on GeoMesa's Gitter, we figured out
that as GeoMesa moves to GT 15/GS 2.9, GeoMesa would need to
update the Joda time dependency to 2.8 or 2.9.
Let me know if there's a better practice or thing I can do to
help out, etc.
Cheers,
Jim

Version hell:
- Guava --> migrate to Java 8 (conflict with ElasticGeo and
GeoMesa). Consder removing as.
