Error while creating Acceleo project [message #1816243]

I followed all the steps in the tutorial below to create my first project in Acceleo:
https://wiki.eclipse.org/Acceleo/Getting_Started
Everything is OK and i have started writting my templates

The probleme is when i run the project i got the errors :
-An exception occurred while dispatching debug events.
-Problems occurred when invoking code from plug-in: "org.eclipse.debug.core".

Note that i followed all the steps in the tutorial , i do all necessary modifications in the generate and manifeste file

I can't understand what is the cause of those errors and i prefer to fix the problem before i complete the writting of my templates.

I am really confused, waiting for your suggestions
In advance thanks for your help

Hi

Your report contains very little information beyond "it doesn't work". Which of "all the steps" failed? How did you do the modifications? What versions are you using? Your screen shot suggests Acceleo 3.3.0 which is seriously old. 3.7.8 is current. Java 11 suggests a much more recent Eclipse.

org.eclipse.debug.core suggests you were doing some debugging which is certainly not an early step. You can find threads identifying debugging problems.

You might find https://wiki.eclipse.org/OCL/ForumNetiquette helpful.

Hello,
Thanks Ed Willink for your reply.

I am using the acceleo 3.7.8, i didn't notice that the version mentionned in the manifeste file is 3.3.0. I corrected it imediately.

Before writting my templates i tried first to generate a file which contains the name of my model and a simple text" I hope it works".

The file was generated correctly. When i use Java strategy for the generation i don't have any error but when i use Acceleo Plug in strategy i have errors.

In the manifeste file i added:
- org.eclipse.uml2.uml.resources,
-Automatic-Module-Name: IPselection

In the generate.java
- i discommented : UMLResourcesUtil.init(resourceSet)
- i changed @generated to @ NOT generated

also in the class path i added the bin directory

Best regards

Hi

The Acceleo Plugin launch has been broken for many (at least five years).

https://bugs.eclipse.org/bugs/show_bug.cgi?id=395726#c2

suggests that the UI has been changed to strongly discourage it.

Please raise a Bugzilla identifying where you failed to get a warning and where a tutorial recommended you do something that should be discouraged.

Regards

It probably doesn't need correcting. To a casual reader the 3.3.0 is ambiguous as exact/minimum/compatible match. My dependencies are always two-ended such as

bundle-version="[2.9.0,3.0.0)"

. If I read the spec or was able to load your MANIFEST.MF, I could tell what it actually specifies.
