Complete deletion of Dev studio and reinstall did the trick. It is now working.

Sometimes it helps to clean the plugin cash in Eclipse. This can be done by adding the parameter "-clean" to the shortcut that starts the NWDS.

Hi,

This is reproducible. Can anyone confirm that this happens (or not) on their systems as well ?

Instructions:

In 'Development Configurations Perspective':

Local DC's view, open 'Local Development', open 'MyComponents', right click on 'MyComponents', select 'Create new DC'. Give name 'extlib', select 'External Library'. Click 'Finish'.

Right click on the newly created DC in the Local DC's view and select 'Build'.

Result:

Duplicate technology definition: 'sap.com/tc/bi/javatech'

...

Warning: Could not validate DC meta data, no information available for type 'External Library'

Regards,

Jari
