Hi,

after updating to nightly 2.7.0 I get this error trying to generate the language:
This stops me totally, so any ideas are desperately welcome...

Hi Ingo,

it appears that some EMF proxy is not resolved in your workflow. Could
you try to debug and check which EClass / GenClass couldn't be resolved?

Regards,
Sebastian

Hi, thanks for the answer.
For now I switched back to 2.6.2 where everything works as expected. When I try 2.7 again I will debug that, if it is still there Smile

Hi Sebastian,

I have the exact same NPE described by Ingo since I upgraded from 2.6.2 to 2.7.2 (and I am completely blocked and may also switch back to 2.6.2 very soon if this issue is not fixed ASAP...)

I can debug for you, but where do I find out exactly which EClass/GenClass couldn't be resolved ?

I attached the value of outputStream (in ECoreResourceFactoryImpl.doSave() line 401) when the NPE is raised, maybe this could be helpful to you.

best regards,
Benoît

additional info on this issue :

actually this issue is also reproducible with xtext 2.6.2 + ECORE 2.10.1.

This issue's root cause is ECORE 2.10.1 (it works ok with ECORE 2.10.0) and not xtext 2.7.2

This could be this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=445659

Sorry about that. Xtext 2.7.2 can be used with EMF 2.10.0, too.

yes it looks like the same bug. at least the good news is that it is fixed.

BUT my actual initial issue remains, see below. My maven/tycho build is still broken Sad
