Hi Lars,
To play with TweetHub, you just need these 3 bundles:
org.eclipse.ecf.provider.twitter.ui.hub.product
org.eclipse.ecf.provider.twitter.ui.hub
org.eclipse.ecf.provider.twitter
Although you need to have ECF stuff, and that is the reason why you got
that error, because TweetHub is built on top of ECF, then it depends of
ECF presence API[1] and others. My suggestion is you download ECF[2] or
checkout the ECF stuff(source code) through ECF psf file on releng
bundle[3].
Please let me know if TweetHub works for you.
Cheers,
- Marcelo
