Maven vs regular eclipse project

Hello,
I was recently browsing plugin tutorial on bukkit wiki, and I've seen that it tells users to create Maven projects.
When i was learning, the regular Eclipse project was shown and advised to use.
Are there any disadvantages or differences between using Maven and Regular Eclipse project?

 

Maven is love, Maven is life. While it is a tad harder to use, dependency management is rather easy (since you don't have to download dependencies as long as there is a Maven repo of it. You simply change version numbers and let it download the new jar for you)

 

Maven makes it easier to collaborate or transfer projects to other systems. It will handle a lot of repetitive tasks on build, so it can increase your productivity, without requiring input beyond setting it up. It doesn't do anything that you couldn't do manually, though, so it comes down to preference and your willingness to give yourself a migraine to spare yourself future ones.
