You need to move the rules inside /src/main/resources/ and maven will
include the rule file into the classpath automatically.

I'm still having problem unfortunately.. :(
i get a strange error that i didn't got before turning to maven:
when running:
kbuilder.add(ResourceFactory.newClassPathResource("src/main/rules/
sample.drl"), ResourceType.DRL);
this errors occurs:

i see a difference between the .classpth and .project files in both
projects (Drools project vs Maven Project).
could this be the reason?

OK, the eclipse maven plugin added those deps type as 'pom' instead
of 'jar',
so the drools jars weren't included.
fixed that.
thanks.

OK, Still got problems.
i've created a maven project, and all looks good in compile time

but i think i still missing a 'runtime' dependency, cause when i try
to run the Hello World example, i get this error:

I always prefer to create the maven projects from the scratch. You
only need to add the following deps (groupid and artifactid)
org.drools
drools-api
org.drools
drools-core
org.drools
drools-compiler
You probably need to add the jboss repository as well in order to get
this deps
