Description

On heavy multi-module build with important number of dependencies the part of ivy might be very important.

On my benchmarked project, ivy take 50% of the time. This percentage is actually more than 80% when test are disbled.

My script make a resolve, use artefactproperty, retrieve the dependencies, compile, jar and publish localy the result. The compilation is done using CachePath.
This is done on +/- 100 interdependant modules, that use +/- 60 additional external dependencies.
The build is launched from a root script that use BuildList.
The dependencies that are not build are taken mostly from a shared drive, and occasionaly (a few that I still have to install on the shared repository) from the maven central repository.

I will attach to this issue some performance enhancements.
