Hi Jean-Philippe, To pickup new updates, then you should use KieScanner (part of kie-ci project) which allows you to do incremental build if a new kjar has been published/released. Here is an example : https://github.com/droolsjbpm/drools/blob/master/kie-ci/src/test/java/org/kie/scanner/KieScannerIncrementalCompilationTest.java
