When compiling decision tables without drools-decisiontables in the classpath you should get an decent error messages telling that drools-decisiontables is missing in the classpath (a missing dependency) ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2996 URL: https://issues.jboss.org/browse/JBRULES-2996 Project: Drools Issue Type: Enhancement Security Level: Public (Everyone can see) Reporter: Geoffrey De Smet Assignee: Mark Proctor Priority: Optional drools-compiler uses reflection to load classes from drools-decisiontables When that fails, because a user project only depends on drools-compiler (which doesn't depend on drools-decisiontables), an understandable error message should be thrown, noting that drools-decisiontables isn't on the classpath. -- This message is automatically generated by JIRA.
