title: How do I tell ivy4r to stay offline?
body: <p>We recently switched from Ant to Buildr for building our projects. We use Ivy for dependency management, using the ivy4r Buildr extension. We have a local repository at the office which is used as a cache for public artifacts and in which we also publish our own artifacts.</p>
  
  <p>Now for the problem: I'd like to be able to build my project when I do not have access to the office repository. Buildr has a flag to tell it to work offline (<code>-o</code>), but ivy4r does not seem to take this into account. Is there any way to make Ivy not try to download artifacts? I have them all available in the cache on my machine already.</p>
