Calling KieScanner throws ClassNotFoundException - maven

Question

I have several Drools projects and would like to be able to dynamically load rules changes. The projects all work fine until I tried to add KieScanner to them. I followed the directions here: http://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html/DroolsReleaseNotesChapter.html#d0e515
I am using drools 6.1.0.Final with Wildfly 8.0.0.Final
The documentation indicates that having the dependency for the kie-ci in my class path was enough. Clearly either I am doing something wrong or the documentation is wrong.
The project builds but when it is called, I get this trace:
10:21:17,946 ERROR [io.undertow.request] (default task-2) UT005023: Exception handling request to /catalog/vetec/search/facets/term: org.jboss.resteasy.spi.UnhandledException: javax.enterprise.inject.CreationException

This business rules project is itself incorporated into the actual WARs that are deployed to Wildfly.This is the dependency used in the application poms:
<dependency>
<groupId>com.sial.rules</groupId>
<artifactId>sial-rules</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
I recently discovered that the extra dependency breaks our Arquillian Unit tests. Since Arquillian has a completely different maven integration, my best guess is that this is a bug in KIE. It is very similar to BZ1098018
Adding this extra dependency "fixes" the issue when the code actually calls kie-ci, however with this dependency our Arquillian tests fail to deploy.
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-aether-provider</artifactId>
<version>3.0.5</version>
</dependency>

Answer 1

You should not need to declare the additional maven, aether and other dependencies manually. The kie-ci should transitively depend on everything it needs. If you look at the pom.xml of the kie-ci https://github.com/droolsjbpm/drools/blob/6.1.0.Final/kie-ci/pom.xml the dependencies you added are also listed there, so Maven resolves them automatically.
This seems to be either some weird bug or misconfiguration. I presume you have the following in your pom:
<dependency>
<groupId>org.kie</groupId>
<artifactId>kie-ci</artifactId>
<version>6.1.0.Final</version>
</dependency>
Could you post your whole pom?

Answer 2

The problem is that kie-ci includes an older version of maven (3.0.5) than does Arquillian (3.1.1) Specifically the maven-aether-provider. Arquillian (really ShrinkWrap) really wants to use the newer version.
I tried forcing the 3.0.5 version in the pom.xml but get the issue of the resolver.
This is the error:
java.lang.UnsupportedOperationException: Unable to boostrap Aether repository system. Make sure you're running Maven 3.1.0 or newer.
So basically kie 6.1.0.Final is incompatible with Arquillian 1.1.5.Final
I will have to see if the Kie 6.2.0CR3 release will work
