Hi,

Further to my last post, which concerned running ETL via ANT, I have
another quick question when using EGL.

I have a simple .launch file that successfully triggers EGL and generates
some output. However, when I try to replicate the task using ANT, I get an
exception. The ANT contains the following:

...
<target name="main">
<epsilon.egl src="PrintExample.egl">
<model ref="APreviouslyLoadedModel"/>
</epsilon.egl>
</target>
...

And the exception I get is:
[simple.egl] EXCEPTION: java.lang.NoClassDefFoundError:
org/eclipse/epsilon/egl/EglModuleImpl
[simple.egl] at
org.eclipse.epsilon.workflow.tasks.EglTask.createModule(EglT ask.java:25)
[simple.egl] at
org.eclipse.epsilon.workflow.tasks.ExecutableModuleTask.exec uteImpl(ExecutableModuleTask.java:75)
...

I'm probably making another basic error, but I couldn't find the source of
the problem elsewhere, so thought I'd try here again.

Best,

Edd

Your Ant script looks fine.

It looks like the Ant runtime can't locate the EGL plugin.

Are you running the Ant script from the same workspace that you used to
successfully execute the EGL transformation using the development tools?

Could you export a copy of your project and post it here for us to explore?

Cheers,
Louis.

Hi Edd,

Looking at the stack trace it seems that it can't find the class
EglModuleImpl (which hasn't been around for a while). May I ask how you
have installed Epsilon (update site, plugins or via SVN)?.

Cheers,
Dimitrios

Hi Dimitrios,

Yes, I noticed that I couldn't find EglModuleImpl in the Epsilon jars...

I installed it at the MODELS conference, end of September / beginning of
October, this year. The version that I have is 0.8.1.1, and it was
installed via the update site as described in the installation
instructions.

Ta,

Edd

Hi Edd,

Could you please update to the latest 0.8.2.1? This should fix this problem.

Cheers,
Dimitrios
