Can't install due to missing xerces plugin

[memelet]

I'm can't get past the install due to missing xerces 2.8.0 plugin. But I have that plugin installed via WTP/GEF/EMF/et all. I have even verified by looking at the installed plugins list.

I would try non update manager, but can't seem find that type of package on the springide site. Is there one? Is anybody else having this issue?

Any help would be much appreciated.
