Sorry, I have no idea about using Eclipse for LibreOffice extension 
development.  From the below exception, it looks like that 
OpenOffice.org Eclipse integration you link to above might not actually 
work with LO.  (The program/types.rdb in LO is in a different format 
than what it was back in OOo.  LO usually treats those different formats 
transparently, but apparently something does not work well in 
combination with that OOo Eclipse integration.)

I see 
<https://wiki.documentfoundation.org/Development/Extension_Development#Eclipse_Plugin> 
mentioning something supposedly LO-specific for developing extensions 
with Eclipse.  Have you checked that out?
