java - Cannot Get JARs from Maven for ElasticSearch Shield Plugin

Question

I'm not able to get maven to pull this dependencies.

<dependency>
   <groupId>org.elasticsearch.plugin</groupId>
   <artifactId>shield</artifactId>
   <version>2.4.1</version>
</dependency>

The only 2 files that are in the folder are:

shield-2.4.1.jar.lastUpdated and shield-2.4.1.pom.lastUpdated

What could have gone wrong? Here's the URL to the repository.

https://mvnrepository.com/artifact/org.elasticsearch.plugin/shield/2.4.1
