If you have the current revision of the zip handy, you can use the Ivy buildnumber Ant task and compare on that. Another option may be to check the timestamp of the current zip and compare it to the timestamp of the zip after it's resolved.
Depending on your build, you may also be able to use Ivy's triggers (http://ant.apache.org/ivy/history/latest-milestone/settings/triggers.ht ml) to do the unzip after the first download (the post-download-artifact trigger). If I recall correctly, the trigger won't fire if you already have the artifact in the cache. -----Original Message----- From: Leamon, Pat [mailto:pat.lea...@sensis.com.au] Sent: Tuesday, January 11, 2011 12:10 AM To: ivy-user@ant.apache.org Subject: Managing external tool with ivy Hi, I'm trying to manage versions of a tool used as part of the build process, not a dependency of the app itself. I've packaged it into a zip and put it into our local repository. This zip is then resolved by ivy and the appropriate version is downloaded, then the build itself unpacks the zip ready for the tool to be used. At the moment I'm doing an ant <condition/><filesmatch></condition> to check if the tool zip has changed since the last build (I keep a copy when I unpack it separately). This saves me unpacking it every build, but since the tool zip is large I still get a 5-10 second penalty for the binary file comparison. Is there any way I can get feedback from ivy to say if the dependency has changed? Thanks, Pat Sensis.
