How do you get Maven to download dependencies from the maven central repository? I have been trying to get dependencies to work for three weeks now and I am at the end of my rope. I have tried three ides, Netbeans, Eclipse and Intelij and none of them can download any sources from Maven as they all fail. All I am trying to do is get a rest api to pull json data from github. I am attempting to use rallyRest to do so and have code that should work. I have attempted an approach with JAR files but there are too many transitive dependencies to have that work. None of the ides will tell me why the Maven repo download fails. This is driving me literally insane, can anyone help with this issue? It occurs on every computer I own so it is something that I am missing but cannot find the correct information anywhere as the documentation for Maven is the worst I have ever seen.
