16.4.2.1. 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.

16.4.2.2. 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: https://web-cat.org/eclstats

• 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 ‘https://web-cat.org/’ 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.
