We could keep the configure task for BC, and define settings however we want since it's new in 2.0. The problem is more related to Ivy design. In Ivy original design I tried to make using Ivy as easy as possible. Hence if you want to use the default settings, and have an ivy file called ivy.xml in your basedir, then using Ivy is as simple as: <ivy:retrieve /> I think this has been appreciated by our users from the beginning of Ivy. Behind the scene, this is roughly equivalent to: <ivy:configure /> <ivy:resolve /> <ivy:retrieve /> But I don't know if people would complain if we were now using the settings as any other datatype in the "Ant way". But I think that actually loading the settings only when they are used is counter intuitive... maybe because I'm too biased by usage of current Ivy design for more than 3 years now. So I think this is a difficult design choice: make Ivy more compliant with the Ant way, or keep a usage as it is used by some people for years, people who haven't complained about this point yet AFAIR. It's difficult to choose, and it's probably why we have discussed this so many times so far. Xavier
