>            Reporter: Luca Molteni
>            Assignee: Luca Molteni
>            Priority: Major

> Currently the kie-maven-plugin avoid generating and compiles FEELExpression from DMN  such as 
> ```
> import static org.kie.dmn.feel.codegen.feel11.CompiledFEELSemanticMappings.*;
> import org.kie.dmn.feel.codegen.feel11.CompiledCustomFEELFunction;
> import org.kie.dmn.feel.codegen.feel11.CompiledFEELExpression;
> import org.kie.dmn.feel.codegen.feel11.CompiledFEELSupport;
> import org.kie.dmn.feel.lang.EvaluationContext;
> public class TemplateCompiledFEELExpression implements CompiledFEELExpression {
>     /**
>      * FEEL: 20
>      */
>     @Override
>     public Object apply(EvaluationContext feelExprCtx) {
>         return K_20;
>     }
>     public static final java.math.BigDecimal K_20 = new java.math.BigDecimal(20, java.math.MathContext.DECIMAL128);
> }
> ``` 
> These are jitted at runtime.
> We could compile them in kjar to have a faster runtime
> Poker: 5
