JavaFx installaion returns Cannot perform operation. Computing alternate solutions, may take a while: 15/15

Question

I am using Windows 7 Ultimate edition Java 10.0.2 Eclipse OXYGEN.3A (April 2018) Version: Oxygen.3a Release (4.7.3a)

When I try to install the JavaFx from the location http://download.eclipse.org/efxclipse/updates-released/1.2.0/site/

then I got the following

Cannot perform operation. Computing alternate solutions, may take a while: 15/15

Cannot complete the install because one or more required items could not be found.
  Software being installed: e(fx)clipse - IDE - PDE 1.2.0.201501301049 (org.eclipse.fx.ide.pde.feature.feature.group 1.2.0.201501301049)
  Missing requirement: JDT UI Tooling for JavaFX 1.2.0.201501301049 (org.eclipse.fx.ide.jdt.ui 1.2.0.201501301049) requires 'bundle org.eclipse.xtext.xbase.lib 2.7.1' but it could not be found
  Cannot satisfy dependency:

    To: org.eclipse.fx.ide.jdt.ui [1.2.0.201501301049]
  Cannot satisfy dependency:

    To: org.eclipse.fx.ide.basic.feature.feature.group 0.0.0

What requirement am I missing.

You do unterstand, that the version of e(fx)clipse you're attempting to install is basically years old!

For example check here - the updates-released section shows versions up to 3.3.0 with a fairly recent date feature_3.3.0.201805280700.

So either use this or use the marketplace entry (which seem to point to version 3.0.0) - drag and drop the install button into your running Eclipse instance or use the marketplace from within Eclipse itself (Help menu, as far as I recall or installable) and search for efxclipse.
