Glenn J. Mason commented on IVY-1176:
-------------------------------------
I've just hit this exact issue when trying to avoid certain steps in my build
using <uptodate>. Specifically:
1) publish a new SNAPSHOT upstream - the timestamp is updated in the repository
(but the revision stays the same)
2) resolve for a downstream module - new SNAPSHOT is downloaded but
ivy.deps.changed=false
I wanted to use this for those odd cases where the upstream change means the
downstream module needs recompilation, but without change in the module itself
- I was hoping to avoid <javac>ing everything every time (although I think it
avoids recompiling if it doesn't have to?).
Any reason ivy.deps.changed doesn't consider the timestamp?

> Hi,
> I am having the same Issue as Jan Vissers on the mailing list:
> http://mail-archives.apache.org/mod_mbox/ant-ivy-user/200803.mbox/%[email protected]%3E
> http://mail-archives.apache.org/mod_mbox/ant-ivy-user/200803.mbox/%[email protected]%3E
> The problem is, ivy.deps.changed does not get set to true if the timestamp of
> the dependencies ivy.xml got updated.
> The call to resolve actually tells me that the new files got downloaded
> (because of the updated timestamp), but ivy.deps.changed tells me that the
> artifacts did not change.

> This behaviour makes ivy.deps.changed mostly useless for me to implement a
> lazy build mechanism in a multi module project.
