Context: I'm working through the example in GMF eclipse series book.

There is an example in the book that lists a sample Worfklow file. This
sample has:
<component class="org.eclipse.xpand2.Generator">
<metaModel id="mm"
class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel " />
<expand value="pmw2csv::Main FOR model" />
<outlet path="${out}" />
</component>

Since in Eclipse 3.5 we're now using QVTO, is this correct? I 'm
thinking xtend isn't used any more?

I can't find any resources with samples for Workflow Engine
configurations for GMF 2.2. Any pointers much appreciated!

The workflow engine was just re-incorporated into the DSL Toolkit
http://download.eclipse.org/modeling/amalgam/dsltk/downloads /drops/S20090703
-0844/index.php using Galileo bits. So, it should be possible to use the
workflow examples from the book in Galileo (though I've not tried it).
You'll have to ping the EMFT newsgroup to get updated advice on using MWE,
I'm afraid.

But yes, I'd suggest using Ant to produce workflows using QVTO and GMF's
Xtext tasks. The only examples I have are the Amalgam build scripts, e.g.
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.amalgam /releng/org.ecli
pse.amalgam.releng/generate.xml?root=Modeling_Project&vi ew=markup

Well, I'm not sold on using the MWE, ANT is fine with me :)


Now I have this whole PackageNotFoundException I mention in my other
post. Oh well, it can't all be easy :) I will be studying you Amalgam
project to figure this one out as well I guess.

Note for others following in my footsteps:
1. Interestingly enough the eclipse.org/gmf/2008/xpand:template ant task
is not included in either the 3.5 DSLTK or the 3.5 Modelling Tools
releases. I had to download the standalone gmf xpand dist just to get
that plugin (org.eclipse.gmf.xpand.ant).
2. If ANT still complains it still can't find the above task, switch
your ANT JRE to the same as the workspace.

Hi

Just to let you know, I was in a similar position a few weeks back.
I posted a lot of my adventures on the emft group, I got the MWE method
working eventually on Amalgam after loading MWE & M2T.


Strangely, my plugin works on Amalgam, JEE, Birt, C++ versions of
Galileo after I configured them them with MWE & M2T myself.
But doesn't produce output on the Modeling version of Galileo
(ie version with pre-configured GMF, MWE, Xpand etc)

Plus if you are using OS X there are also some gotchas.

If I could just the pesky filterexpression for CNF working I would
be happy - last thing to do!

regards
Steve

While running my generate.xml ant script I'm getting NPE on some emf
class, when I try to debug off the Ant script it will not stop on any
breakpoints, so I can't debug it :(

Any hints on why this is the case? I've debugged code launched form Ant
a bazillion times and this is a first.

p.s. If I click on 'Run Configurations' there is no listing of any Ant
targets, they only way I can get to it is via a right click on
generate.xml? odd!

Try using 'External Tools Configuration' run option, and not 'Run
Configurations' to see the Ant targets.

Also, make sure under JRE tab you're using the 'Run in the same JRE as the
workspace' option.

Course turns out you can't do that if you are wanting to debug a Ant
Task itself.

Lucky for me this is a documented issue:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=24130#c6

Comment 6 did the trick for me:
