Convert POM dependencies to SBT dependencies using the ammonite REPL. Useful when trying to migrate a project from maven to SBT.

PomToSBT.sh

#!/usr/bin/env amm

// This script converts Maven dependencies from a pom.xml to sbt dependencies.
// It is based on the answers of George Pligor and Mike Slinn on http://stackoverflow.com/questions/15430346/
// - install https://github.com/lihaoyi/Ammonite
// - make this script executable: chmod +x PomDependenciesToSbt
// - run it with from your shell (e.g bash):
// $ ./PomDependenciesToSbt /path/to/pom.xml
