building my project from scratch doesn't work [message #1710800]

Hi!

I have a project where I define my own ScopeFragment. The associated class refers to classes in the model, but these don't exist when building from scratch so the build fails.

If I comment out the Scopefragment in the mwe2, run it then remove the comment and run the workflow again, then it works. But it doesn't feel like it should be like this (if in the future a new maintainer gets in and I'm gone from the project, they won't understand why they can't build).

Is there some way to go around this issue?

best regards,
Vlad

hi you have to move own fragments to a separate bundle that is built first

@Christian Vlad's problem is that his Fragment has hard references on the model classes of his language

@Vlad If there's not too many references, then using String constants would be the simplest thing. Or if the code is more generic, you can access the Grammar and generate code for each rule, like the ContentAssistFragment does

Thank you very much, I'll check ContentAssistFragment.

Hi!

It's been a while since I asked this, but I've been sidetracked. I still have some things that I'm confused about.

When I do a clean ckeckout from my repo, if I generate the language infrastructure, the mwe2 script complains that it can't find my ScopingFragment. I need to do a clean rebuild of the project (even though 'build automatically' was enabled) and then generate. Is this to be expected? Can I ensure somehow that the project is built before generating?

While it's not a very big deal when building manually, I am worried that when I finally get around to implementing the headless build, this issue will create problems...

best regards,
Vlad

As i said. You have to move the fragment to a own module that has to be uilt first.
Then add a dependeny from the module with the workflow to the module with the fragment

Yes, but in Eclipse I still need to do a clean build to make sure that the fragment plugin is built. I suppose that having a differnet plugin will help in the headless case, which is the important thing.
Thanks and merry Christmas!

Hi i dont understand that. You dont have to do a clean build. Eclipse will pick up the fragment fron the other project.

Well, what happens for me is that after "git clean -fdx", I refresh all workspace, then start the mwe2 workflow and get "class not found MyScopeProvider". I do a clean build of the workspace and after that it works as expected. Maybe something is weird with my settings...

Cany you share a sample project thst reflects your setup

Thank you very much Christian, I will get back to you with this if it still bugs me, but I just went on vacation Smile

I think the setup is pretty ordinary, but maybe the OS or the file system or Java are not working together nicely.

Vlad
