Ignasi Barrera commented on JCLOUDS-1225:
-----------------------------------------
Hi [~ian.springer]. I'm sorry you are having trouble with this. In fact it is
really simple, and if you copied the example I provided from the Jenkins
project, you should have it working. I'm going to paste it here, with minor
amendments so you can easily directly copy and paste this without having to
tweak it. This si a pretty common configuration of the maven shade plugin.
*Pom to create the jclouds shaded jar*
This shaded jar will contain:
* The Guava version used by jclouds, with all its classes relocated to another
package
* All jclouds classes with all references to Guaca updated to use the relocated
package.
This will let jclouds use the version of Guava it needs, and you will be able
to configure Guava 21 in your project without package collisions.
*NOTE* That there is no need to relocate the jclouds classes; just Guava to
avoid collisions between the version in your project and the version in the
shaded jar. This why you can reference the jclouds classes as usual, using
their standard package.

*Pom file to use in your project to include jclouds*
Instead of including each jclouds dependency (all them should be now configured
in the pom.xml above), just depend on the jclouds shaded jar.

As you can see, it depends just on the jclouds shaded, and it has all the
jclouds transitive dependencies *except Guava*, which is the dependency that
conflicted with your project, so you're free to add the Guava version of your
choice now.
Could you try this configuration?
> Guava 21 compatibility

>
> Key: JCLOUDS-1225
> URL: https://issues.apache.org/jira/browse/JCLOUDS-1225
> Project: jclouds
> Issue Type: Improvement
> Components: jclouds-core
> Affects Versions: 2.0.0
> Reporter: Ian Springer
> Labels: guava
>
> The below classes use com.google.common.base.Objects.ToStringHelper, which
> has been deprecated since Guava 18, and has been removed in Guava 21. This
> makes it impossible to use jclouds in a project using Guava 21. Please either
> upgrade to Guava 18+ and switch to using
> com.google.common.base.MoreObjects.ToStringHelper, or drop the usage of
> ToStringHelper altogether. This will allow my project to upgrade to Guava 21
> without having to use a fork of jclouds.
