Hello Epsilon experts,
I am very new to epsilon stuff especially to Eugenia. I am trying to re run the example given in screen cast (filesystem project) on official website. I can sucessfully create filesystem.gmfgraph, filesystem.gmfmap, filesystem.gmftool. for generating filesystem.gmfgen i run the wizard. In example video the transformation step is done automatically and no qvto transformations (prepost-reconcile) is required. yet the filesystem.gmfgen model is created. I how ever tried to workout without qvto transformation by selecting java i get this error message
i get the following error message:

" org.eclipse.m2m.internal.qvt.oml.compiler.QVTOCompiler.compi le(Ljava/lang/String;Lorg/eclipse/m2m/internal/qvt/oml/compi ler/QvtCompilerOptions;Lorg/eclipse/emf/common/util/Monitor; )Lorg/eclipse/m2m/internal/qvt/oml/compiler/CompiledUnit; "

I don't know how to continue from here or is there a complete project with qvto transformations which i can understand as a starter example with and without qvto transformation.

best regards
saad

Hi Saad,

I must admit I've never encountered anything similar before. Which
version of Eclipse/GMF are you using?

Cheers,
Dimitris

(Hi, my first post to this forum, so apologies if I've not used correctly.
Running Eclipse Epsilon, from the epsilon-0.9.1-win32.zip build.)

I have attempted to run the Eugenia 'filesystem' example, second screencast example. Two questions:

Q1 is there an insistency between the filesystem.emf code as listed in the screencast, versus that available in the cvs filesystem? For instance, first 12 lines of the file code reads:

@namespace(uri="filesystem", prefix="filesystem")
package filesystem;

@gmf.diagram(foo="bar")
class Filesystem {
val Drive[*] drives;
val Sync[*] syncs;
}

class Drive extends Folder {

}

while on the screencast, the first 3 lines read:

@namespace(uri="filesystem", prefix="filesystem")
@gmf
package filesystem;

i.e. there is an extra '@gmf' line?

Q2 When I put my code in Eclipse following the example, but exactly as the cvs file, I get an error highlighed with red x at line 12:

"Encountering "Class" at line 14, column 1.
Was expecting on of:
<EOF>
"@"...
(etc) "

Q3 What in the screencast is the GMF project given such a long/esoteric name:
"gmf.eclipse.epsilon.eugenia.examples.filesystem"
-Is this simple because of how you are organising your examples, rather than literally how a user might need to name it to get it to work?

thanks
Julian

Hi Julian,

Q1: The @gmf line is not used by the current version of EuGENia and can be removed.

Q2: The version of Emfatic that is bundled in the Epsilon distribution does not support detail-less annotations. As such, even when no details are needed for an annotation, a dummy detail needs to be added (e.g. foo="bar")

Q3: That's just the the naming convention we use for our examples.

Cheers,
Dimitris

Thanks for your quick reply.

Q1 OK
Q3 OK

Q2 I understand your reply, but don't know how it relates to the problem (the error) I described. I just re-ran up the same point (loaded the annotated filesystem.emf) on a different PC, and that is not flagging up an error. I'll investigate further...

Julian.

Hi Julian,

Different behaviour in 2 PCs most probably indicates either different versions of Emfatic or a bug. I'd add at least one detail to each annotation just to be on the safe side.

All gmf lines have at least one annotation, if I understand your suggestion.

Attached (if I'd done it right) is a screen dump of what I see on my company PC. The hover text over the red 'x' reads:

Encountered "Class" at line 14, column 1.
Was expecting one of:
<EOF>
"@" ...
"package" ...
"abstract" ...
"class" ...
"interface" ...
"transient" ...
"datatype" ...

What now (to get this working)?

Julian.

Hi Julian

just my 0.38 CZK (2c) - probably EMF is case sensitive and you have some class defined with capital C.
