Hi,
I have downloaded a eclipse amalgamation package (i.e Helios) and today I dod an online software update which worked. So I should have a current up to date Acceleo inbstallation. I am using the documentation in "Acceleo Quickstart" from here ( http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse. acceleo.doc/doc/overview.html ) but no matter what I do I cannot get the Run As | Launch Acceleo Application to work. The system launches, the run Configurations screen appears but the "run" button does nothing ( the documentation has a "run" button but the application has apply and revert as well ). No code is generated. I have waited for 10 minutes for something to happen but nothing does. Running it from Debug As produces the same result. The eclipse error log does not have any obvious problems .
So... does anyone have any ideas on a troubleshoooting startegy so I can get Acceleo working

Hi,

We tested Acceleo on Helios and I have never seen this problem. I have two theory for this one, a new bug or a mistake that can easily be made. Let's start by being pessimistic:

Does the same thing occurs if your create your run configuration from scratch ?
Menu "Run" (not Run As on your project but Run at the top of the Eclipse window) then "Run Configurations...", then right click on "Acceleo Application" and "New", and then you have to select:

1- The acceleo project
2- The java class generated by Acceleo. This Java class has been created by Acceleo because in one template of one of your modules you have a [comment @main/]. This Java class is located in the same package as your module with your main template and it should have the same name as your module.
3- your model
4- your target folder

And then you can just click run. The generation should work. If it does, then I have an idea on what append previously, but if it doesn't could you please upload a picture of your Run Configuration.

If it worked, then I think that when you selected Run As on your project, Acceleo tried to look for the Java class that launch the generation and for that a window appears with the available Java files. You may have selected another Java class and not the Java class of your main module. In such case Acceleo cannot launch the generation.

Anyway, we you hit Run, the Acceleo engine is initialized and the generation starts it should not take more than few seconds. For example, I took 10s to initialize the generation and 9s to generate 200k lines of code today for me, so no need to wait for 10min.

Stephane,
These problems are normally "user error" or "user misunderstanding".

I have done as you asked and theresult is the same. I have created a PDF of the screen dumps etc but I cannot find out how to attach the file to the message. The help says ".... brose at bottom of page..." but I do no have a browse at the bottom of the page

Hi Daniel

If you're using Windows, it is well worth learning to use

C:\Program Files\HTML Help Workshop\flash.exe

which allows you to cut and paste and clip screen shots.

You can then just paste the screen shot into an HTML mail posting.

Hi,

You can upload a screenshot on this site for example an then copy here the link: http://uppix.net/ or http://imageshack.us/

Does the problem appears if you create a new project from scratch and if you create a very simple ecore model with one class for example ? (with a package name, a uri, and a prefix).

Does the problem appears with one of our example ? (file -> new -> example)

I created a project from an example as per. "Installing an Example Acceleo Project" fro mthe Acceleo USer Guide

( http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse. acceleo.doc/doc/overview.html)

and the result was the same

Hi Daniel,

Your generation modules (mtl files) are taking their types from the Ecore metamodel (the "http://........../2002/Ecore" part of your modules' signatures), yet you feed them an "UML" model for the generation.

Your template would generate a file for an "EClass" in the source model, yet your UML model can't have any EClass : it will have "Class"es instead.

You can either change your sample module to take its type from the UML metamodel instead of Ecore, or change the sample model you feed the generation to be an ecore model instead of an UML model.
