Description
The EC2 plugin is currently throwing the following error while trying to launch a build slave:

The AWS API docs specify EC2 hostnames like the following:
... ec2.eu-central-1.amazonaws.com ...
So, the "ec2" and "eu-central-1" portions are flipped. I recommend that the API endpoints are updated to use the hostnames that are currently outlined in the API docs.

added a comment - Unfortunately there are some regressions in the current master unreleased version. I'm going to try and address those in the next few days and once they are fixed and it seems reliable, I will do a new release.

added a comment - I'd like to second bbl5660 here and hope that the regressions are smoothed out soon. The new release would save us a great deal of testing time if we can boots the slaves in the same data center as our master.

added a comment - I have finished my work on 1.30 snapshot, I would like some additional testing before I make the release, which I can do any day now.

It would be really great to see a new release of this plugin. My team has seen a few issues working with the ec2-plugin, and we're hoping things will get smoother soon. On GitHub, there have been 14 commits to the master branch since the last release (August 2, 2015). One notable change (IMHO), is that the aws-java-sdk dependency has been upgraded from version 1.10.2 (used in the last release) to 1.10.26 (currently in the master branch).
Can someone please comment as to when an update is expected, or if another plugin should be preferred?
