I got the following exception when trying to add a package to a RuleBase
org.drools.rule.InvalidRulePackage: Rule Compilation error
org.drools.spi.KnowledgeHelper cannot be resolved to a type
at org.drools.rule.Package.checkValidity(Package.java:378)
at org.drools.reteoo.RuleBaseImpl.addPackage(RuleBaseImpl.java:303)
...
Anyone knows what could be the problem? It is a unit test which runs OK in
Eclipse, but fails when running from the command line, even classpath is the
same.
Sorry about the lack of details. Have to run now. Will provide more info
later if necessary.
Thanks,
Yuesong
