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#

Creating a new Maven Module

• 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 and hit Next
• Check the checkbox called "Create a simple project (skip Archetype selection)", give the project a "Module Name" and hit Next (see the example on the screenshot on the right).
• Enter a human-readable name into the field "Name", fill in "Description" as needed. For Plugins, the module name must start with d3web-Plugin or KnowWE-Plugin.
• 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.

Manually adding .settings and target to svn:ignore

Or (compare with the screenshot on the right):

• 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#

Enabling the plugins that are to be built in the Run Configuration

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.

Troubleshooting#

Eclipse does not catch breakpoints#

Update your JDK to at least Version 6, Update 17.

java.util.MissingResourceException: Can't find bundle for base name...#

Happens after cleaning the workspace. Solution: For each of the two maven super projects (d3web, d3web-KnowWE), select the project, right click on it, "Run as..." → "Maven package".

Offline Build (if Artifactory is not available or you have no Internet connection)#

Create a second runtime configuration for building KnowWE, just like shown here: http://d3webwiki.informatik.uni-wuerzburg.de/Wiki.jsp?page=Workspace#section-Workspace-CreateARunConfigurationForBuildingTheWiki, just check the "Offline" checkbox.

Note: Do not enable this option for your regular build, only use it if Artifactory is down or you are not connected to the internet!

Problems with Umlauts#

Tomcat can be configured in UTF-8 to handle Umlauts correctlty. Look at http://www.jspwiki.org/wiki/BugProblemsWithGermanUmlaute
