problem executing .eol with ant [message #515970]

hi all

i tried to run an .eol file from ant (as shown in the epsilon book, page 165), but it seems it could not find the epsilon.eol task.
autocompletion of 'epsilon.eol' works in the editor, so i'm not sure what's the problem.

my .ant file:

<project name="MyProject" default="main">
<target name="main">
<epsilon.eol src="test.eol"/>
</target>
</project>

error message:

BUILD FAILED
C:\workspace\test\build.xml:3: Problem: failed to create task or type epsilon.eol
Cause: The name is undefined.

thx for your help

marco

Hi Marco,

You need to select the "Run in the same JRE as the workspace" option
under the JRE tab of your launch configuration (see
http://eclipse.org/gmt/epsilon/doc/workflow/)

Cheers,
Dimitris

thanks dimitris

now i have another question, that is...
if i want to work on an ecore file within my .eol file, do i have
to load this model via 'epsilon.loadmodel', or can i just use it?
(they're both in the same folder)

i get

EXCEPTION: Type 'Ecore!EPackage' not found...

but maybe it's just that i try to access the .ecore in the wrong way?
i'm not sure

thanks again...

marco

Hi Marco,

Yes. You need to load it first. Here's an example:

<project default="main">
<target name="main">

<epsilon.emf.loadModel
name = "Ecore"
modelfile="foo.ecore"
metamodeluri="http://www.eclipse.org/emf/2002/Ecore"
read="true"
store="false"/>

<epsilon.eol>
EClass.all.size().println();
<model ref="Ecore"/>
</epsilon.eol>

</target>
</project>

Cheers,
Dimitris
