3.4. Installing the Web-CAT Submission Plug-in for Eclipse

3.4.1. Introduction

Here are instructions for how to install the Web-CAT submission plug-in for Eclipse. These instructions assume that you are running Eclipse versions Oxygen or Photon.

Note: This might be a good time to also update Eclipse. If you are running a version earlier than Oxygen, then you should install the latest version directly. If you are running Oxygen or Photon already, then you can check for updates at Help --> Check for Updates.

3.4.2. Installing the Plug-in Un-Installing an Old Plug-in

If you already have an earlier version of the Web-CAT plug-in installed, you will first need to uninstall it. For those installing it for the first time, skip to the section on Installing the Plug-In.

Open Eclipse, and in the tool bar at the top of the screen, go to Help --> About Eclipse IDE. Then click on the button that says Installation Details. A window something like this should come up:


Select Web-CAT Electronic Submitter and click Uninstall. Follow the prompts, clicking Next and Finish as appropriate, and restart Eclipse to complete the process. If you don’t see a line labeled something like Web-CAT Electronic Submitter then you probably do not have the Web-CAT plugin installed. Installing the Plug-in

Open Eclipse, and in the tool bar at the top of the screen, go to Help --> Install New Software. The following window will come up:


In the Work With text box, paste this link:

  • Next, click Add. A dialog box will pop up with two text boxes.

  • Make sure the above URL is in the box labeled Location, and put in a sensible name (like “Web-CAT plugin”) in the box labeled Name.

  • Once that’s done, click Add.

This is what the window should look like now:

  • Check the boxes next to Web-CAT Electronic Assignments Feature and Web-CAT Java Development Extras, and click Next.

  • It will then tell you about files that it plans to install. Click Next.

  • Accept the terms of the license agreement, and click ‘Finish’.

The install will start now.

This might take some time depending on your internet connection. Probably at least once it pause and warn you that you are about to install software with unsigned content.

If this is your first time installing the plugin, then You are likely to get a window titled Trust Authorities that looks like:


When it does this, select the checkbox next to ‘’ and click the Trust Selected button.

At some point while downloading the plugin files, you might get another window titled Trust Artifacts that looks like:


If so, check the boxes and click the Trust Selected button. The install will continue. Restart Eclipse when prompted to complete the process. Final Setup

Once you have the plug-in installed, you need to set it up to be able to communicate with Web-CAT:

  • Go to Window --> Preferences (Eclipse --> Preferences on Mac).

  • In the window that comes up, in the column on the left, click on Web-CAT Assignments. You should see this window:


Put in the following information:

3.4.3. Installing student.jar

If you are using Web-CAT, then you probably will want to use the VT local support for JUnit tests.

First, download the student.jar file.

Then, in Eclipse, right click on your project, and navigate to Build Path --> Configure Build Path. In the window that comes up, click on the Libraries tab. Select Classpath and click Add External JARs. Navigate to the location where you saved the student.jar file, select it, and click Open. The student.jar file should now be listed in the Classpath section as shown below:


Now click Apply and Close to complete the process. You should now be able to use the VT local support for JUnit tests.

See here for some practical advice on getting started with JUnit testing. At the time of this writing, the prefered version of JUnit to use is Junit 4.

3.4.4. Installing formatting support

You might want to make sure that your Eclipse style checker is as close as possible to the style guide that Web-CAT is enforcing. Download this file: vtcsstylefixed.xml (Right click and Save-As). Then install it into Eclipse, as described below.

Once it is installed, press CTRL-SHIFT-F (Windows) or COMMAND-SHIFT-F (Mac) within Eclipse to format your code.

To install:


Eclipse->Preferences->Java->Code Style->Formatter->import the above file, then click okay.


Window->Preferences->Java->Code Style->Formatter->import the above file, then click okay.
