sbteclipse-plugin;4.0.0: not found

Hi, I just tried the plugin as mentioned in README to put that line into plugins.sbt. It's failure to run eclipse and got following information:
[info] Resolving jline#jline;2.12.1 ...

what should I'm going to do for fixing this?

Thanks,

Start with the README instructions for adding sbteclipse-plugin to plugins.sbt and reproduce the failed resolution with Scala 2.11 and sbt 0.13. Check the dependency coordinates and the unresolved-dependency report; done means the documented setup resolves successfully and runs Eclipse.
