Graphical plugins are loaded in headless mode

[RoiArthurB]

Is your request related to a problem? Please describe. GAMA headless is loading some useless graphical plugins from GAMA (opengl and java2D; and probably swt and other) which are useless for an headless usage...

Describe the improvement you'd like Having only a define and explicit list of plugins loaded with GAMA headless: namely, only the one mandatory to have a gaml file compiling and executed.

Describe alternatives you've considered It is possible to limit packages loaded by manually removing those jar files from the plugins folder at the root gama installation folder 🤷

Additional context Example of the logs of the headless runing the validate function

$ bash headless/gama-headless.sh -validate

Actually, the only plugins that should be loaded are the ones present in the features that do not contain ui in their name.

   <features>
      <feature id="ummisco.gama.feature.dependencies" version="1.9.0.qualifier" installMode="root"/>
      <feature id="ummisco.gama.feature.core.extensions" version="1.9.0.qualifier" installMode="root"/>
      <feature id="ummisco.gama.feature.core" version="1.9.0.qualifier" installMode="root"/>
      <feature id="ummisco.gama.feature.models" version="1.9.0.qualifier" installMode="root"/>
   </features>

Loading the others in headless is kind of a nonsense, and we need to understand where it comes from.

EDIT: with @RoiArthurB, we may have found the solution, which is to create a new product without any ui features. More on this later ! The log is a bit lighter indeed:

Yes, that 's what i want to say. And we should have also the headless release version aka compact/mini, too, for later container's developement.

@RoiArthurB when can we expect to have the new product / launch config for headless in order to test it in different setups ? AFAIK, the only thing needed on Eclipse side is to remove the ui features and run the product. On the command line side, probably there is some need to change the scripts (but I would bet it is just a matter of renaming the launch configuration to use in headless...

[AlexisDrogoul]

@RoiArthurB what is the progress on this ? Do you think we could test something today ?

[RoiArthurB]

Hey guys, long time not answered but working on it.

So far, here where I am :

i.e. It works inside Eclipse; but the version built with maven doesn't... I keep exploring each potential issue, but the more it goes and the more I start to think that the problem might come from something else than the headless package (as I really dug pretty much everywhere there) :/
