Red Hat Bugzilla – Bug 966300
ResourceChangeScanner marks Guvnor URLResources (package source and binary) as "removed"
Last modified: 2015-12-04 10:19:44 EST
Description of problem: Platform BZ for https://issues.jboss.org/browse/GUVNOR-1699 How reproducible: Always Steps to Reproduce: 1. Use KnowledgeAgent with ChangeSet.xml which points at "http://localhost:8080/jboss-brms/rest/packages/mortgages/binary" or "http://localhost:8080/jboss-brms/rest/packages/mortgages/source" <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd' > <add> <resource source='http://localhost:8080/jboss-brms/rest/packages/mortgages/binary' basicAuthentication='enabled' username='admin' password='admin' type="PKG" /> </add> </change-set> 2. Let it scan Actual results: scan fails to detect the resource and assume it was removed. So empty kbase is built.

Additional info: <resource source='http://localhost:8080/jboss-brms/org.drools.guvnor.Guvnor/package/mortgages/LATEST' basicAuthentication='enabled' username='admin' password='admin' type="PKG" /> works. But some customers prefer "http://localhost:8080/jboss-brms/rest/packages/mortgages/binary" because it makes package building happen as well.
GUVNOR-1699 has been fixed for Guvnor 5.4.0 but this use case doesn't work yet. I have filed https://issues.jboss.org/browse/GUVNOR-2014 about the detail.
Toshiya Kobayashi <tkobayas@redhat.com> made a comment on jira GUVNOR-2014 Attached a reproducer which works with mortgages sample.
I dont think this bug is relevant to 6.0. The whole build system is changed, as well as the REST API. For example, we do not provide REST API for package based resources (we do not have "package" anymore in 6.0): URL http://localhost:8080/jboss-brms/rest/packages/mortgages/binary
Thanks for the info, closing.
