IntelliJ / Niagara Module Plugin

Question

I'm receiving the following error while attempting to sync gradle in JetBrains IntelliJ while trying to work on a Tridium Niagara project.

Error

Build file '<<project_path>>\build.gradle' line: 1

A problem occurred evaluating project ':dcEclypse-rt'.
> Could not resolve all files for configuration 'classpath'.
   > Could not find com.tridium:niagara-module-plugin:3.0.18.

What I've Tried

My solution references {NIAGARA_HOME}/niagara.gradle which references a local maven repository:

maven { url "${rootProject.ext.niagara_home}/etc/m2/repository" }

I've confirmed that the jar in question is at:

etc\m2\repository\com\tridium\niagara-module-plugin\3.0.18\niagara-module-plugin-3.0.18.jar

Unfortunately, its .pom file is being sought instead. Do I have to do something to index this repository?
