Mongodb-Hadoop connector version error

Question

I am trying to connect hadoop to mongodb on windows. I have the version 2.3 of Hadoop and I change the build.sbt file so I have this

hadoopRelease in ThisBuild := "2.3"

And yet when I try to run this command

sbt package

I keep getting this error message, despite the fact Hadoop is up and running with the 2.3 version.

[debug]

I am following this tutorial, however it's a bit outdated since the connector already supports the version 2.3 http://docs.mongodb.org/ecosystem/tutorial/getting-started-with-hadoop/

Answer 1

Use gradle to build. Gradle is the official way to build it now. I'm waiting to remove the sbt stuff until the doc changes get pushed to that url. The github page has the up to date instructions.
