xtext validation not working on new installation #280

Closed lesquoyb closed 3 weeks ago

lesquoyb commented 1 month ago

Describe the bug It's an issue that is not happening on all computers, I just noticed it on my home computer but everything works fine on my work computer. I have some models that just cannot be validated by xtext when I run gama from eclipse. The models themselves do not show any error but I can't see any experiment button, and I get this error message when I open a new one in the editor: image The stack in eclipse is this:

!MESSAGE org.eclipse.xtext.builder.clustering.ClusteringBuilderState  - Error validating platform:/resource/Generated%20From%20Serialize/models/Serialize%20Tests.experiment

!STACK 0

I made sure to clean the project and recreate a new gama workspace but I have exactly the same problem.

To Reproduce Steps to reproduce the behavior:

  1. Maybe create a new eclipse workspace ?
  2. run the latest version of gama from git
  3. try to open the model Clean Line Network.gaml
  4. See error

As a note, there's no problem on the same computer with the release of last month so either it's something specific to eclipse or it's from a commit that happened during that time span.

Expected behavior I can run my models as I could before

It just disappeared after some time and I'm now able to compile this model on the same computer. Closing it for now and I will reopen in case I found a way to replicate
