Java introduced the assert keyword, so the way to enable source-level support is to make sure that Eclipse's Java compliance level is 1.4 or higher. (The chances are that the compliance level is already higher than that ...)

To cause a Java application launched from Eclipsed to run with assertion checking enabled, add the "-ea" argument to the VM arguments in the launcher configuration's "Arguments" tab.
