Subject Re: Downloading new snapshot (trigger by timestamp)
Date Fri, 14 Jan 2011 16:33:32 GMT
Hi,

Yes, but I would like to avoid cleaning the cache everytime. This idea is
that Ivy just checks if some of the content of the cache has actually
changed on the nexus repository. If I clean the cache everytime, I'll end up
download everything, everytime.

I just tried adding  checkmodified="true" on my resolver :

<url name="my-resolver"
      changingPattern="\*-SNAPSHOT"
      changingMatcher="regexp"
      checkmodified="true"
      m2compatible="true">

But sadly, as you suspected, Ivy does not treats pom.xml like ivy.xml in
this regards...
