MoJ Assignment Plugin Manual

How to install and use the MoJ Assignment Plugin.

Installing the plugin

This is the usual unzip in your Eclipse directory. If everything went well you should have a mojAssignmentPlugin_1.0.0 in your plugins directory. Now (re)start your eclipse and proceed to: Window->Preferences->Java->Installed JREs. Edit the active JRE and add the lib/tools.jar of your JDK to its classpath. This makes sure that the java compiler can be executed.

Dont forget to add tools.jar to your JRE

Starting a new MoJ Assignment Project

This can be done easily using the New MoJ Assignment Project wizard. Select File->New->Project.. and the following dialog will appear:

Finally specify the Name, Display Name and Author of the assignment and press Finish.

The wizard will setup the directory structure, classpath and some template files for your assignment. Two source folders will appear. The first contains the source files that will be visible to the player (including the file that needs to be edited). The other folder (ending with Test) contains the code for the test-cases.

Developing your MoJ Assignment

The MoJ Assignment plugin has support for two new launch types. One is the Run as Tester.Testable which executes the xxxTester class and displays the description and performs each of the tests of the assignment. The other is Launch in MoJ and starts the MoJ Server and Client simultaniously and starts the game. You can login using a default username and password which will be filled in for you.

Also available are some consistency checks for the manifest file of the assignment. If an entry has an incorrect value or needs to be present an error or warning will appear in the Problems tab of the IDE.
