[recommenders-dev] Problems building source from eclipse workspace

[Gerrit Freise <gerrit.freise@xxxxxxxxxxxxxx>]

Last days I want to build the source code from eclipse workspace under 
eclipse 4.2 M6, using the follwing manual 
(http://wiki.eclipse.org/Recommenders/BuildingFromSource).
I have fetched all dependencies and setting up the workspace's target 
platform (e42-devel). Now I have the following problems:
1) Its impossible for me to start the e42 target with the Option 
-XstartOnFirstThread (unrecognized option under windows & linux)
2) After removing this option, I'm getting the folowing Exceptions (see 
http://dl.dropbox.com/u/20854023/1336861896959.log):
..
"java.lang.ClassNotFoundException: org.eclipse.swt.widgets.Display"
...
"java.lang.ClassNotFoundException: org.eclipse.swt.widgets.Display"
...
"java.lang.ClassNotFoundException: org.eclipse.swt.SWTError"
...

I'm using eclipse 4.2 M6

can s.o. help me?

cheers, Gerrit
