What are the steps to install the third-party VSS plug-in into JBuilder?
Please note that this plug-in is not certified by CodeGear, and thus technical support for it is not offered.
Go to Help | Software Updates | Manage Configuration
Next, make sure the "Show Disabled Features" button is selected, and expand the "...\JBuilder200?\thirdparty\eclipse" node.
Finally, scroll down and select "VSS Plug-in Functions for Eclipse <version>", and then in the right-hand pane, click on "Enable"
Restart JBuilder when prompted.
