Drools unable to compile rules when using a declared enum in the DRL file ------------------------------------------------------------------------- Key: DROOLS-4307 URL: https://issues.jboss.org/browse/DROOLS-4307 Project: Drools Issue Type: Bug Reporter: Robert Buchmann Assignee: Luca Molteni Priority: Major Attachments: drl.zip I am finding inconsistent behaviour between drools reading rules from a local file (as a fileSystemResource) as opposed to pre compiling the rules into a kjar. This happens if I use an enum declared within the drl file in the "when" or "then" section of a rule within the same drl file. The rule runs perfectly as expected if I load the rule from the filesystem, but fails to run if I have pre-compiled the rule. For this reason I think this is a bug as I would expect the same behaviour for both ways of running rules. I outlined the problem in more detail stackoverflow: https://stackoverflow.com/questions/56989080/drools-maven-plugin-not-unde... This is running JAVA8 and drools 7.23.0.Final
