Javadoc
Returns the ordered list of all the package patterns used to define the set of resources that have
to be included in the KieBase. If this list is empty, "*" is assumed by default, meaning that
all the resources stored under a folder with the same name of this KieBaseModel will be
included in the compiled KieBase regardless of the package they belong to.
The list of package patterns is ordered and earlier patterns are applied before later patterns.
For example, if you specify "org.foo.*,!org.foo.impl" the second pattern has no effect since all org.foo
packages have already been selected by the first pattern. Instead, you should specify "!org.foo.impl,org.foo.*",
which will export all org.foo packages except org.foo.impl.
