Error in executable model generation when trying to bind an enum value

Solution Unverified - Updated -


Building rules written in MVEL dialect and trying to bind an enum value with executable rule model enabled causes an error.

When I build a maven project which contains rules trying to bind an enum value like (*1) with executable model enabled,

package com.example.reproducer

import com.example.reproducer.Bus

dialect "mvel"

rule "bus2"
       $bus : Bus( $maker : Bus.Maker.HINO )    // ..... (*1)
       System.out.println("bus=" + $bus + ", maker=" + $maker);

// Maker.HINO is an enum value declared in Bus class.

build error occurs with the message like below.

$ mvn clean compile -DgenerateModel=YES
[ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.44.0.Final-redhat-00003:generateModel (default-generateModel) on project your_project: Execution default-generateModel of goal org.kie:kie-maven-plugin:7.44.0.Final-redhat-00003:generateModel failed.: CannotConvertException -> [Help 1]
