However, I saw some people using maven doing it. I intend to take the opportunity to learn maven. However, I don't get why bothering using maven. It seems a drag.

What I forgot to mention the other day, and what is one of the core
features of Maven, and certainly one of the most attractive ones, is
dependency management.

That I forgot to mention it is quite telling - what can often develop into
a nightmare of copied jar files, directories full of differently named
versions, and spreadsheets about what dependency is needed by another
dependency, and what jars to include at compile time, or run time, or both,
commonly referred to as "dependency hell" is something that Maven just does
for you.

It does it so well that I didn't even remember that that was ever an issue.
If I need a library in my project, I just copy 4-6 lines into my pom.xml
configuration file (usually available on the libraries website), and Maven
does the rest for me - search for it on the net, download it, place it
whereever it belongs, and when I make a jar or war, puts it into the jar or
war (or not, depending on whether it's needed).

And what is more: it also deals with all the dependencies THAT library may
have - no longer need I worry about whether hibernate-core.jar needs
apache-logging.jar, or maybe a specific version of log4j2.

Naturally, that is less of a concern if you already have a complex
application set up the way you want it, so it seems less like a fantastic
feature and more like a burden.

Liebe Gruesse,
Joerg
