!!1. Allocation
Every project has to be allocated to one of the three main repositories:
* __d3web-core__
* __d3web-KnowWe__
* __Reasearch__

!!2. Creating the project in Eclipse
* Do a right click on the main project (one of the three projects mentioned above) → New → Other… (or press Ctrl + N). In the window, select Maven → Maven Module
* Check the checkbox called "Create a simple project (skip Archetype selection)", give the project a "Module Name" and hit Next
* Enter a human-readable name into the field "Name", fill in "Description" as needed
* Click "Finish". 
You will see the new project in the Eclipse Project Explorer. Now you can start creating or copying source files. Using the __UTF-8 encoding__ is __mandatory__

!!3. License Header
Every {{.java}} file must contain the license header, starting in the first line. Be sure to have an empty line between the license and the {{package}} declaration.

The license has to look like this:
{{{

}}} 

!!4. First Check-In
You have to perform the first check-in using the chosen main repository (c.f. above).
* Right click the main project → Team → Commit
* Now __exclude__ the folders {{target/}} __and__ {{.settings/}}! (Uncheck the check boxes)
* Enter your commit message (comment) → Commit 

Now you can enable SVN access directly for your newly created project: 
* Perform a right click on the new project → Team → Share 
* Select SVN, you will find the repository location already set up 
* Hit Finish.

To complete the process, you have to ignore {{target/}} and {{.settings}} permanently. There are two ways to do this:

Either:
* Select both folders in the Project Explorer with Ctrl/Command, right click → Team → Add to svn:ignore. Click OK in the window that opens.
Or:
* Right click on your project → Properties
* In the window, select SVN Info on the left
* In the table at the bottom, double click on the line with name "svn:ignore"
* In the new window, enter ".settings" and "target" __separated by a newline__ in the "Enter a property value:" field
* Hit Ok twice

Finally, commit the ignore settings: right click → Team → Commit. Enter a commit message like "ignores" and press Ok.

!!5. Selecting plugins to build

You need to enable the plugins you want to build into KnowWE when using Eclipse. Here's how:

Open your Run Configuration for the KnowWE build by Hitting Run As... → Run Configurations... and add parameters for the plug-ins you want to have.

For instance: You want to enable the Comment plug-in. Here, you have to add a comment-plugin parameter. You can set it to an arbitrary value ('true' for instance).

See the screenshot on the right for another example.
