Spring Maven - Unable to generate WSDL

I'm trying to generate the WSDL from a URL but it's/I'm unable to do it. My POM.xml file is configured like this:

I resolved all the errors that occured in the POM.xml file and jaxb2 is recognized. When i run "maven generate-sources" i get the following output:

[WARNING] The URI [http://ift.tt/1Awbc9H] seems to represent an absolute HTTP or HTTPS URL. Getting the last modification timestamp is only possible if the URL is accessible and if the server returns the [Last-Modified] header correctly. This method is not reliable and is likely to fail. In this case the last modification timestamp will be assumed to be unknown. [ERROR] Could not retrieve the last modification timestamp for the URI [http://ift.tt/1Awbc9H] from the HTTP URL connection. The [Last-Modified] header was probably not set correctly. [WARNING] Last modification of the URI [http://ift.tt/1Awbc9H] is not known.

But i have no clue how to solve this. The same soap service is used in this Spring Guide

(I had to change the url in error message because i can't post more than 2 links)
