Hi all,
I have a project where there are 3 grammars: Datatypes, APP, and System. The App cross references entries from datatypes and System cross references entries from APP.
I am trying to create a standalone generated for System Models. Based on available information, I have called the 3 standalone setups. Then I am passing all the related models (for all of the 3 grammars) into the main file. And I am loading them using injectors specific to the grammar.
For example
injectsystem = new SystemStandaloneSetup().createInjectorAndDoEMFRegistration()
injectapp = new AppStandaloneSetup().createInjectorAndDoEMFRegistration()
injectdata= new AppStandaloneSetup().createInjectorAndDoEMFRegistration()
.... and
var resourceSetSystem= injectsystem .getInstance(typeof(XtextResourceSet))
var resourceSetApp = injectapp .getInstance(typeof(XtextResourceSet))
var resourceSetData = injectdata.getInstance(typeof(XtextResourceSet))
...
then
for (arg : args) {
... do some processing to get ext (extension)
if(ext=="sys")
{
resourceSetSystem.getResource(URI.createFileURI(arg), true)
}
else if (ext=="app")
{
resourceSetApp .getResource(URI.createFileURI(arg), true)
}
else if (ext=="dt")
{
resourceSetData .getResource(URI.createFileURI(arg), true)
}
}
However, when I try to run the validator on the system model it gives me errors that the references cannot be resolved. I think I understand why it is happening. However, I am not sure how to resolve the references across the three resourcesets in the standalone mode.
Thanks for your help.

the problem might be the way you create the executable jar file.
there are multiple plugin.properties files that overide each other
=> you have to merge them
=> or use something like the gradle application plugin (that created a java ap with -classpath, so the plugin.properties will not be merged
=> maybe there are options to do this on maven as well
