[cross-project-issues-dev] EMF GWT

[Ed Merks <ed.merks@xxxxxxxxx>]

I'm considering dropping support for EMF's GWT components from EMF 
2.14.   If you don't care, don't read any further because I'll interpret 
silence as not caring.

The problem is that I'm still using very old versions of GWT and 
AppEngine tools.  These tools are broken in the latest Oxygen release 
because of methods removed by JDT:

java.lang.NoSuchMethodError:

So I can no longer use a development environment newer than Neon to work 
on them.

Also the tools have been migrated to new versions hosted at other 
locations.  I think I could get most of this working with the latest 
tools, but org.eclipse.emf.server.ecore.resource.DatastoreUtil uses 
com.google.appengine and the tool for that now requires one to install a 
Cloud SDK separately rather than embedding an SDK (or whatever is needed 
at compile time) in the Eclipse bundle. Setting up such a development 
environment is a PITA and also doing so for the Tycho build is a second 
PITA.

Does anyone care?

Ed
