Hi guys,

MWE 20090725 appears broken on my install. M20090729-0903 Its looking
for a (very) specific version of commons.lang that apparantly isn't
there..

Missing requirement: MWE Core (Incubation) 0.7.1.v200907251900
(org.eclipse.emf.mwe.core.feature.group 0.7.1.v200907251900) requires
'org.apache.commons.lang [2.1.0.v200803061811]' but it could not be
found

thanks,

Miles

its never a good idea to use a required-bundle dependency if using common things like:

* logging
* apache commons
etc.

If working with some projects and 3rd frameworks,
then you always have problems with those common used dependencies resolved by required-bundle

I opened 3 bugzillas for this about logging against mwe, xpand and xtext. (bugzilla 284714, 284715 and 284716)

Miles, please open a bugzilla to change the dependency to package-import

It's a good point and will do. I can't help but feel a little worry
about this issue altogether, because after all I suppose that it is
possible to have some sort of configuration where noone actually
provides apache commons. :) I do think that at least one should have no
version specified. Unfortunatly PDE complicates this because it always
wants to add in the most exact version. :( Have you come across any
good discussions of this?
