I just tried again, now the 'connection timeout' problem is gone, but I get the 
following error/backtrace in the startup task 'Modular API Baseline, activate'. 
How can I get around this?

 Hi,
    I am new to Eclipse/JSDT and have been trying to set up a JSDT development 
environment. I followed the instructions in 
https://wiki.eclipse.org/JSDT/Development, using an Eclipse IDE + a target 
platform. For some reason beyond me, the resulting workspace has 500+ errors 
because it doesn't include plugins like com.google.javascript and com.jboss.*. 
Is there some extra step I need to take to get those components pulled in?
    I have also tried the 'Oomph' approach described in 
https://wiki.eclipse.org/JSDT/QuickStart. The problem I run into there is that 
when the IDE starts for the first time, it fails to download some files because 
of 'connection timeout', and refuses to continue the startup tasks. Any 
suggestion on how I may get around this? Or is there some other approach to set 
this up? Thanks
