Hi,
I'm trying to migrate from GMF 2.1 to GMF 2.2
For the gmfmap and gmfgen it seems to work great but for the templates...
I followed this :
http://wiki.eclipse.org/GMF_Xpand_Migration_howto
But few questions (some just to be sure) :
Do I need to be in Eclipse 3.5 to migrate?
for step : Ensure existing templates present in the workspace and can be compiled
Do I need to change the dependency range for org.eclipse.gmf.xpand? and is it just the template error that we need to avoid?
In the .xpand-root :
"As it was mentioned in org.eclipse.gmf.templates.legacy plug-in description, all legacy templates were relocated to org.eclipse.gmf.templates.legacy plug-in. Nevertheless, original template locations should be used inside .xpand-root file like:
/org.eclipse.gmf.codegen/templates
/org.eclipse.gmf.codegen.lite/templates "
Do I need to set this above in my .xpand-root? if I do that and that I've got the o.e.gmf.codegen project in my workspace there are errors in these templates (ambiguous definition)
or just let :
templates
templates-dynmodel, templates/
After multiple tries, I always have errors in my templates.migrated :
"couldn't find xpt::NativeGenAuditRoot"
"couldn't find NativeMetaModel"
"cannot find operation asValidJavaIdentifier(String) for the type null"
....
So as I didn't modified an lot the templates I tried to restart from the new o.e.gmf.codegen.
But I can't do anything, I have no completion and i have in the error log :

It's a Qvto file, need I to set up QVT Operational builder on this project? How can I do that? In new dialog for builder there is only Operational QVT transformation builder proposed...
Thanks for any advice

Hello Aurelien,

Yes.

Dependency from org.eclipse.gmf.xpand plugin is not necessary for making
custom templates compilable. This dependency is only important in case you
have some java classes working with xpand and in this case I you probably
have to modify used org.eclipse.gmf.xpand version range to [2.0.0,3.0.0)
but it is not necessary for templates migration.

If your templates are referencing/aspecting some other templates from /org.eclipse.gmf.codegen/templates
template root then you should place this root into .xpand-root file in the
project with custom templates to make legacy template be compiled without
any problems.
Usually .xpand-root file should contain something like:
templates, /org.eclipse.gmf.codegen/templates
This meand you have /tempaltes folder in this project and this folder is
used as a root for all the custom templates (specified in .gmfgen model).
in addition templates from this root aspect/orevvide original templates from
/org.eclipse.gmf.codegen/templates. This information is (and always was)
necessary for xpand editor to be able to correctly compile templates/show
corresponding errors.
I suggest you to close o.e.gmf.codegen (and other projects with unnecessary
metamodels/templates located in your workspace) during templates migration
step. Sometimes meta-model files from this plugin (gmfgen.ecore/gmfgen_2008.ecore/gmfgen_2007.ecore)
can be loaded and used by xpand template builder/migration tool in conjunction
with meta-models located in platform:/plugin so there will be a clashes leading
to some compilation problems.
> After multiple tries, I always have errors in my templates.migrated :
So, you was able to migrate legacy templates without migration problems,
but you got some compilation problems in a migrated templates?
This can happen in this case you probably have to review migrated templates
contents and make them compilable again...
> "couldn't find xpt::NativeGenAuditRoot"
Native "escapeXML" query from this file was relocated to gmf::CodeGenerationUtils
> "couldn't find NativeMetaModel"
Native queries from this file were repackaged: "getGetAccessor" query was
moved to gmf::GenModelUtils, "safeName" - to gmf::CodeGenerationUtils
> "cannot find operation asValidJavaIdentifier(String) for the type
This query should be called "validJavaIdentifier" from now and it is in gmf::CodeGenerationUtils
As you can see we've changed some native queries just after templates migration,
but if you can migrate your templates without migration errors then it probably
means the rest should be fixed manually.

Looks like XPAND editor you are using came from some older GMF.

This will be done for you by migration tool.
you need this builder only to see compilation errors in QVTO files. (xpand
files will be compiled even without this builder.

Thanks for all your help. All works fine.
For the XPand editor, I think that I had to restart Eclipse but now it works. And just a question about it, is there an outline? Or do I need to fill an enhancement bug?
