This is in a way a follow-up of a previously unanswered question of mine ([link](https://stackoverflow.com/questions/3238644/adding-user-defined-libraries-to-svn)) which excalated over the past weeks, and now it has come to a point where I cant really develop anymore... 

So here's the deal; I have more of a mathematics/engineering background than pure CS, so I dont have a lot of experience with proper/large-scale software development, but rather scripting and algorithms. Now that I am working on a large project, on my own, I am confused with some of the aspects of development. One of them being **handling libraries/dependencies**

I have initially created a folder called `lib` under my project folder (in Eclipse workspace) and copied my external libraries in there and then added them to the build path. However later on I needed some other stuff like `JCommons`, `JFreeChart`, `Apache Commons Math` etc.. According to instructions these libraries can/should be included as user libraries, allowing the developer to see the documentation and source code from within IDE (such as Eclipse). I have gotten it right so far, I hope... 

So where is the problem? Well first off it appeared as the user libraries mentioned above are not included on the SVN copy of the project, meaning that my colleagues who wanted to test-drive my project couldn't do so, by just simply acquiring the project from SVN. Now the second phase of the problem unsurfaced when I changed my workstation at work, I wanted to import my project into Eclipse from my backup, but then everything except those user libraries are there. To make things more complicated, when this software is done, it will be implemented on a server so it would be absolutely best if everything could be packed into one single library or a even better a runnable `jar` file.

I have been previously advised to take a look at Maven, or Ivy, but my initial understanding after checking them both is that they are used from the beginning and mostly for more complicated projects. Honestly I am completely puzzled as to how I am supposed to manage my dependencies. Any ideas? 

(Sorry for keeping it long, but I figured better complete and long then inadequate information) 

**EDIT:** I have managed to sort out the problem; the problem has apparently originated from the simple fact that eclipse doesn't copy all resources to one place, and the installation instructions for some libraries doesn't really warn you about how to manage the libraries in the best way. 

Thanks to everyone, who took their time to try and help me. I will in time look more into projects like Maven and Ivy, it's definitely interesting stuff. However for now I just need to get back to the software into running state, been wrestling with new stuff for too long.. :)
