.resolve(dependencies, sources) ⇒ Array<String>

Resolve dependencies, downloading from sources.

Uses a separate JRuby runtime to avoid polluting the classpath with Aether and SLF4J classes.

(likely jar files) satisfying the dependencies

Parameters:

  • dependencies (Array<Hash>)
  • repos (Array<String>) —

    urls to maven2 repositories

  • dependency (Hash) —

    a customizable set of options

Returns:

  • (Array<String>) —

    an array of paths to artifact files
