Migrating from buildr buildfile to gradle

Question

I currently have a project with lots of modules and dependencies using buildrBuildfile. For numerous reasons, we would like to transfer the project to gradle.

Is this possible in a simple way? Should we rewrite the Buildfile to a file build.gradle?

I searched everywhere but nobody seems to have this problem. I should not attach the Buildfile, as this is a corporate project, although I consider its exact content to be useless.
