Missing cascading repository in installation instructions

[bobrik]

This is the error I see:

[ERROR] Failed to execute goal on project spark-es-compacter: Could not resolve dependencies for project name.bobrik:spark-es-compacter:jar:1.0-SNAPSHOT: The following artifacts could not be resolved: cascading:cascading-local:jar:2.5.6, cascading:cascading-hadoop:jar:2.5.6: Failure to find cascading:cascading-local:jar:2.5.6 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

And this is how it could be fixed in pom.xml:

    <repositories>
        <repository>
            <id>conjars.org</id>
            <url>http://conjars.org/repo</url>
        </repository>
    </repositories>

I think it should be mentioned in docs.
