Drools - KieServices.Factory.get() returns null ----------------------------------------------- Key: DROOLS-5535 URL: https://issues.redhat.com/browse/DROOLS-5535 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.36.0.Final Reporter: Ashish Srivastava Assignee: Mario Fusco Priority: Major I try to integrate a Drools project in a maven application. The Drools app is running perfectly on his own, but when I try to integrate it in the *quarkus project*, I get a java.lang.NullPointerException. After some researches, it seems to happen because KieServices.Factory.get() return me null because of kie.conf. Drools Site Quote is: Many modules of Drools (e.g. drools-core, drools-compiler) have a file named {{kie.conf}} containing the names of the classes implementing the services provided by the corresponding module. When running Drools in a fat JAR, for example created by the Maven Shade Plugin, those various {{kie.conf}} files need to be merged, otherwise , the fat JAR will contain only 1 kie.conf from a single dependency, resulting into errors. You can merge resources in the Maven Shade Plugin using transformers, like this: ([https://docs.jboss.org/drools/release/7.14.0.Final/drools-docs/html_singl...]) how can we configure the same for Quarkus Project ? or is there any way to load these file externally ..
