Cannot figure out at all, here is the message I get :
"Selection does not contain a main type (@main annotation is missing in your template)"
I've tried many times, with the most simple things ever, it does not want to work any more.
[comment encoding = UTF-8 /]
[module generate('http://www.eclipse.org/uml2/3.0.0/UML')/]
[template public generate(p : Package)]
[comment @main /]
[file (p.name, false, 'UTF-8')]
[p.name/]
[/file]
[/template]
As you see, the annotation is really there.
Step :
* New Acceleo project
* Click finish ()what ever the options are, this is the same)
* Right click on generate.mtl
* Run As ...
* Error message
I was working on a transformation for some time, when I decided to remove it and restart from the ground-up. When I wanted to create a new project, I get this.
It was working fine before, not any more, and it complains about a missing annotation which is there.
Any one already get the same ? How to solve ?
-- EIT --
Here is an error log I get about Acceleo :
"Resource '/org.eclipse.acceleo.module.sample/src/org/eclipse/acceleo/ module/sample/files/generate.mtl' does not exist."
But that file exist, and I've checked the path is good; this is the same path as in the file's properties.
Acceleo seems really confused here (note : I do not know when this error logs line appeared).
-- EDIT (2) --
Seems to have something to deal with the workspace, as if I switch workspace, then the above does not fail. Precisely, the ".metadata" subdirectory of the workspace seems involved.

This work temporarily if I restart with a new workspace, but after some time, Acceleo ends to be always back to the above error.
Am I the only one with this bug ?
I suspected something in the Preferences, but there is no entry for Acceleo there.
Is there a way to attach a file here ? I would like to attach an archive of the ".metadata" folder, as I suspect the cause in somewhere in there.
-- EDIT -- When it fails, there is only a generate.mtl and no Generate.java. So when the workspace contains some stuffs (do not know what), Acceleo does not create the Generate.java when it creates an Acceleo project.

Hi Yannick,
I am quite puzzled as how you could end up with such errors ... Are you
sure you have the automatic build activated (in Eclipse : "Project" >
"Build Automatically" is ticked)? Do you have a "xxx.java" file
generated right beside the "xxx.mtl" file you're trying to launch?
If yes to both ... Could you provide me with the version of Eclipse and
Acceleo you're trying this with?

Great, that was it ! I use to uncheck it for something relying on an external compiler in a specific view, and though this option applied on a view basis. No, seems now it is global (further more, I then hided this option from the menu for all views).
Valuable answer : it solved the trick and it explains why it was not working (I've learned something). Always good to ask an expert.

I had noticed that indeed, in the second message (in the EDIT). But I could not guess this required "Build automatically", as I though this Java file was created in the while during a project creation.
Hope I could contribute one future day, at least to thank.
Have a nice day
