JVMModelInferrer code generation [message #1815479]

Iam using Xtext in my project to generated java classes from the DSL.
Created custom inferrer by extending AbstractModelInferrer.
I have a requirement where i need to generate code using a set of xtext resources. i want to generate a single common class class for all the resource and generate fields in the class for individual resources.

Problem is that infer method is invoked for a single resource so i cannot generate a class that is common across all the resources.

Is there any way that i can infer the resourceSet instead of a single resource

I don't know any possibility to do this with jvm model inferrer.
In General this is possible though (I don't know if you want to call into that multi class, if not you could use it)

Here is a very old blog post https://www.google.de/amp/s/kthoms.wordpress.com/2011/07/12/xtend-generating-from-multiple-input-models/amp/

Old but gold ;-) Might not 100% up-to-date, but the principle is still the same.

Thanks Christian, code generation is possible with the way in your post but the problem is that the single common class generated from all the resources is not accessible in the other generated classes.
Xtext validation fails. It complains for the missing type for the generated class type. I am trying to access the class in the xblockxpresssion .

Code generation will not work if in the generated code we are trying to access the generated common class from all the resources.

As said before!.

(I don't know if you want to call into that multi class, if not you could use it)

The inferrer does not support this usecase
