Binding a list written in MVEL expression causes a build error in executable model.

Solution Unverified - Updated -


Binding a list written in MVEL expression like (*1-1) causes a build error like (*2) in executable model.

(*1) rule

package com.example.reproducer

import com.example.reproducer.Car

dialect "mvel"

rule "rule12a"
        $car : Car( $group : ["compact", "medium", "luxury"] )    // ..... (*1-1)
        System.out.println("***** Which group " + $group + " is " + $car + " categorized into?");


$ mvn clean compile exec:exec -DgenerateModel=YES
[ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.44.0.Final-redhat-00003:generateModel (default-generateModel) on project reproducer_model_compiler_12a: Execution default-generateModel of goal org.kie:kie-maven-plugin:7.44.0.Final-redhat-00003:generateModel failed: Encountered unexpected token: "[" "["
[ERROR]     at line 1, column 10.
[ERROR] Was expecting one of:
[ERROR]     "+"
[ERROR]     "++"
[ERROR]     "-"
[ERROR]     "--"

This issue does not occur in build with executable model disabled.
