Setting up Tortoise

Make a folder to store your datapack. (L2J-Datapack)
Right click on the folder and choose

SVN Checkout

Enter the address. http://www.l2jdp.com/svn


Click Ok.
Let the program download the files.

When done, Click Ok.

Now you have the Datapack. It does not need to be Compiled. All that eclipse did was zip it up and remove the .svn folders.
Open the folder and navigate to \trunk\datapack_development
Install it according to the readme.txt

To Update your Datapack

Right click on your datapack folder and choose
SVN Update
Let the program download the files.

Using eclipse

Basically set it up the same way as you did for the server svn.
Just use the datapack address.
