To whom it may concern,
  I am fairly new to IVY also I am a System Administrator not a developer.  Any 
way we setup a repository and were constantly editing IVY configs and thus  had 
some issues with cache not getting updated.  To work around the issue so we 
were just cleaning the cache with every build to ensure that we got what we 
wanted.  Anyway the repository is fairly stable now and I have time to look 
into the cache issues.  I have included most of my configurations and 
observations below.  Here is the general flow.
 
  * Using Ivy 2.0.0-beta2
  * Update ivy.xml file to include new dependency 
  * Generate new .md5 and .sha1 files
  * Commit the file  (resolved via url from svn)
  * Run ant target to retreive the files
  * Resolve does not download the new depenency
  * Check of cache directory shows that the bda-utils ivy.xml file is not 
updated
  * After much research added ivy.resolver.default.check.modified property to 
try and circumvent cache
  * This resulted in not using the file from the site just using version from 
cache again
 
Anyone have any ideas?
     Thanks, Steve Saksa
