SWT + JFace main library.

1. You can select multiple JAR files from this list by holding down the Ctrl key while clicking. Scroll down the list and select the remaining JAR files. The complete list for Eclipse 3.3 is shown below.
   1. org.eclipse.core.commands_.jar
   2. org.eclipse.equinox.common_.jar
   3. org.eclipse.jface_.jar
   4. org.eclipse.osgi_.jar
   5. org.eclipse.ui.workbench_.jar
2. If there are any other JAR files that displayed for your Eclipse version when you looked at the JFace dependencies above, select them here as well. As mentioned earlier, org.eclipse.ui.workbench is not actually part of JFace but is included here because it supplies some useful dialog classes. When you have selected all of the required files, press OK. The Libraries tab should now show all of the JAR files, similar to the screenshot below.
