Hi,

I just got the newest Eclipse Ganymede Modeling Package and installed
Epsilon via the update manager with it. Now my ant build files don't seem
to work anymore. I get an elaborate error starting with

"loadModels:
[epsilon.loadModel] Internal error:
org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Resource
'../Models/sca_v1_ClassDiagram.uml' does not exist."

for the first model it is supposed to load.

I never encountered this error with the previous versions. Did I maybe
forget to configure/think of something?

Thanks in advance for the help,
Anne

Hi Anne,

If you are using relative paths, you should use the file attribute
instead of the value one. For example

<parameter name="modelFile" *file*="../Models/some.uml"/>

will work while

<parameter name="modelFile" *value*="../Models/some.uml"/>

will not.

Cheers,
Dimitris

Hi Dimitri,

I changed

<parameter name="modelFile" value="${basedir}/CardInsert.uml"/>

to

<parameter name="modelFile" file="${basedir}/CardInsert.uml"/>

but that doesn't change the error I get.

Something else I might be overlooking?

Thanks again and regards,
Anne

Hi Anne,

Could you please zip and send me your project so that I can have a look?

Cheers,

Hi Anne,

Are you by any chance running Linux? If so, you may need to add a file:/
before your path to make sure that the load model task knows that it's
an absolute path. e.g.

<parameter name="modelFile" value="file:/${basedir}/CardInsert.uml"/>

Cheers,
Dimitris

Solved. :)

There was a misunderstanding. My line read:

<parameter name="modelFile" file="../Models/some.uml"/>

which didn't work. But

<parameter name="modelFile" value="file:/${basedir}/CardInsert.uml"/>

works good (On Mac with and without the / ).

Thanks,
Anne

Hi Anne,

Glad this helped :)

The problem is that in Windows you can easily tell if a path is relative
or not e.g. c:/file.txt is definitely absolute while /foo/file.txt is
relative. In Unix-based systems however the latter can be both (thus the
need for the file:/ prefix).

Cheers,
Dimitris

Hi Dimitris,

Actually /foo/file.txt will always be an absolute path on a Unix-based
system. If you want a relative path you need to use foo/file.txt. I
think, Eclipse's standard path handling functions actually use this to
determine if a path is absolute or not, which is why I have found under
Windows you will sometimes have to use paths like /C:/... to make it
very clear to Eclipse that this is indeed an absolute path. Maybe at
some point someone will go in and make sure there is a platform-neutral,
consistently implemented way of identifying absolute vs. relative paths
in Java, but at this point everybody seems to be cooking their own.

Cheers,

Steffen

Hi Steffen,

I agree with everything you said :) I'll put this in my todo list for
further investigation.

Cheers,
Dimitris
