Eclipse and Maven help

I installed Maven yesterday for a big project and I was told Maven would be better for it, because you wouldn't have to use all these Build Paths. I've ran into a big annoying problem with this though, because I'm getting this error in the pom.xml.

Code:

Cannot read lifecycle mapping metadata for artifact
org.apache.maven.plugins:maven-compiler-plugin:maven-plugin:3.0:runtime
Cause: error in opening zip file

This is my first time using Maven, and I don't really understand it, but I've cloned from the Git repo, and imported it as a Maven project, but that error still comes up.
Hopefully someone can help me, thanks
