Major updated Jenkins server but kept Jenkins $HOME from old server. Updated installed plugins including S3 plugin, S3 plugin started throwing errors:
java.lang.NoClassDefFoundError: org/apache/http/conn/scheme/SchemeSocketFactory
java.lang.NoClassDefFoundError: org/apache/http/protocol/HttpContext
I had to drop the httpclient-4.4 and httpcore-4.4 jars from another plugin into the S3 plugin to make it work
[JENKINS-26903] S3 plugin missing http jars

added a comment - Sorry, just seen your link to 'give it a try' above, but can't seem to figure out how.
FWIW, the patch looks fine.

added a comment - Hello Ross,
You can install a plugin manually this way:
1. From the above link, download the .hpi file
2. Manage Jenkins > Manage Plugins > Advanced > Upload
See:
http://antagonisticpleiotropy.blogspot.ca/2014/02/installing-jenkins-plugins-in-servers.html
(Note: If you have the official S3 plugin installed, you should uninstall it first.)
If everything checks out, I can send a message to Jenkins developers group to see if someone can publish a new official release.

JENKINS-26903 - Add missing httpclient-4.4 and httpcore-4.4 dependencies to resolve java.lang.NoClassDefFoundError
Compare: https://github.com/jenkinsci/s3-plugin/compare/ab3afa1be121...845f1bc7765a
I also had to copy the jars from the lib folder of httpclient-4.4 and httpcore-4.4 to the S3 plugin (/var/lib/jenkins/plugins/s3/WEB-INF/lib/) and restart Jenkins for this to work.
