to Drools Usage

Hello everyone, before talking about the problem I am having, I will first explain how we are using Drools:

We have a microservice application, which makes use of JHipster to make our lives easier. Our application is a Spring Boot application that uses Spring Cloud and etc. This application uses Drools and for this we have 2 separate artifacts: a pojos artifact - in the example, drools-problem-pojos, which contains the modeling of the classes used in the Drools rules and a rules artifact - in the example drools-problem-rules, which contains the Drools drl files and kmodule.xml.

So the application has as dependence on pom.xml, the pojos artifact - drools-problem-pojos - and kie-ci, besides other dependencies. The rules artifact - drools-problem-rules - are loaded at runtime through the ReleaseId, which fetches from maven.

Having said that, the following happens:

When pom.xml has normal dependencies, without using dependencyManager, the project works fine as expected. However when using a dependencyManager, like the spring-cloud-dependencies, the application does not even go up. The error below occurs. Has anyone ever had this problem? How did you solve it?

One solution that works is not to use dependencyManager and manually put the version of all the dependencies we use in the project. But this is unfeasible in projects with many dependencies, as is our case. I do not know what else to do.

To illustrate this, I uploaded a working example in my github - https://github.com/elgleidson/drools-problem

The only difference between them is the use of dependencyManager in pom.xml of drools-problema-main-error.

To rund, just do the following:

$ mvn clean install
