PomDependenciesToSbt

#!/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

def main(pomPath: String, path: Path = cwd) = {
  val lines = (XML.load(pomPath) \\ "dependencies") \ "dependency" map { dependency =>
    val groupId = (dependency \ "groupId").text
    val artifactId = (dependency \ "artifactId").text
    val version = (dependency \ "version").text
    val scope = (dependency \ "scope").text
    val classifier = (dependency \ "classifier").text
    val artifactValName: String = artifactId.replaceAll("[-\\.]", "_")

    val scope2 = scope match {
      case "" => ""
      case _ => s""" % "$scope""""
    }

    val exclusions = (dependency \ "exclusions" \ "exclusion" map { exclusion =>
      val groupId = (exclusion \ "groupId").text
      val artifactId = (exclusion \ "artifactId").text

      s"""\n     exclude("$groupId", "$artifactId")"""
    }).mkString

    s"""  "$groupId" % "$artifactId" % "$version"$scope2$exclusions"""
  }

  println(lines.mkString("", ",\n", "\n"))
}

This isn't working for me as-is with Ammonite 0.8.2. But adding "@main" on a line above the start of the main method fixes it. Must have been an ammonite change.

I also needed to import ammonite-ops by adding the line

import $ivy.`com.lihaoyi::ammonite-ops:2.4.1`
