First when trying to use WindowBuilder (SWT) in Eclipse JEE 4.8 you must remove all spaces from your Eclipse folder name that contains all its files. This first step was discovered via link:

Eclipse Photon - Eclipse Marketplace not launching

Secondly, is this link tells the second half of the mystery. If you go to:

http://download.eclipse.org/windowbuilder/WB/integration/4.8/

you will see on the left hand side "show directory contents" which will have "repository.zip" file as last file of this expanded list. Download this (~39Mb). Note path to this file, then in eclipse click on "help" (last menu item), then click on "Install New Software...", then click "add", then click "archive" and go to path of saved "repository.zip" and select it. You will see square check box now indicates file to install.

I believe one must then click "continue" (check box already checked for WindowBuilder install item), then confirm when all files to be installed show are shown on screen, then finally click "finish". After the file is loaded in archive step I am not sure of the exact verbiage used for remaining steps but I believe what I have said is mostly accurate and after adding archive it will be self evident (piece of cake) what steps to follow. Finally to check if Window builder is installed go to (in top menu items) "file" then "new" then "other" and then finally scroll down list and WindowBuilder should be in this list, otherwise you landed a goose egg and something went wrong.
