问题
I am using Kie-CI api to scan the latest ruleset in local maven repository. Kie-CI is not working after upgrading to version 7.5.0. Below is the code I am using. Exception says artifact does not exists but actually artifact exists in repository. KJAR artifact is created using Kie-CI api. Any insights on this would be helpful.
Code:
@Async
@Transactional
public void scanLatestRuleset(String version){
log.info("Request received to activate new ruleset version: [ " + version + " ]");
KieServices kieServices = KieServices.Factory.get();
ReleaseId releaseId = kieServices.newReleaseId( "com.example", "sample-rules", version );
//Using Kie Scanner to activate
this.kieContainer = kieServices.newKieContainer( releaseId );
KieScanner kScanner = kieServices.newKieScanner( kieContainer );
kScanner.scanNow();
}
Logs:

Had the exact same problem.
This seems to be due the jar xerces:xercesImpl:2.11.0.SP5 not being in standard repositories.
As MvnRepository states here, this artifact needs to be picked up from the JBoss 3rd Party repository or some other repository.
