java.net.UnknownHostException: build: nodename nor servname provided, or not known

Tried simple code from the example:

`Map jobs = null;
try {
jobs = jenkins.getJobs();
System.out.println(jobs.keySet());
JobWithDetails ios = jobs.get("My job").details();
} catch (IOException e) {
e.printStackTrace();
}`

Fails with:

Tried to google, found out several similar issues, like [this](http://crunchify.com/getting-java-net-unknownhostexception-nodename-nor-servname-provided-or-not-known-error-on-mac-os-x-update-your-privateetchosts-file/). But **build** is not my hostname and even if I add it to /etc/hosts, this code won't run anyway.

Any idea how to fix this?
