I can't address the bulk of your question, but I did want to mention that t=
his slightly parenthetical issue sounds like a problem with your latest-str=
ategy setting--it sounds like it's using the latest-time strategy instead o=
f the latest-revision strategy.

Subject: Retrieve fails to revert to earlier version

Is it intended behavior that reverting to an older version of a dependency =
requires a clean-lib before retrieve? The RetrieveEngine seem to only check=
 the dates of files when it determines what to copy to the lib dir after a =
resolve.

Example:

1.       Make ivy.xml depend on some module 1.0.

2.       Clean the lib dir.

3.       Running retrieve populates the lib dir with the correct files.

4.       Update the ivy.xml to depend on version 2.0.

5.       Running retrieve populates the lib dir with the correct files.

6.       Revert ivy.xml back to depend on version 1.0.

7.       Run retrieve and see Ivy say that no files are required. The lib d=
ir still contains the 2.0 files.

Resolve will correctly log that it resolves against the specified version a=
nd the resolve log and cache are updated with the correct versions at all t=
imes.

Also, if for some reason the 1.0 version has a later date than the 2.0 vers=
ion, say it's a late bug fix, 2.0 wouldn't overwrite 1.0 in step 5.

My solution at the moment is to have my ant script run a clean-lib if the i=
vy.xml is newer than the lib folder, but it feels like a kludge.
