[rules-users] Drools 5.0 concat string in matches of regular expression

[Lukas Svoboda]

I'm getting some generic not-anything-saying error message:
     [java] Unable to determine the used declarations.
     [java] unexpected symbol ' ' : [Rule name='BL: Block mail domain']

When I remove that concatenated matches expression (".*@" +
blacklistItemValue + ".*") it compiles.

Complete rule looks like:
rule "BL: Block mail domain" ruleflow-group "black-list"
salience 1001
	when
		not RejectionResult();
		
		customer : CustomerPartyDRL();
		blackList: BlacklistDRL();

		onBlackList : ArrayList( size > 0 ) 
               from collect( BlacklistItemDRL( blacklistItemType matches
"MAIL_DOMAIN" && customer.currentContactInformation.partyEmailAddress.email
matches blacklistItemValue )
                             from blackList.getItems())
	then 
		auditLogger.addDeclineRule( "BL: Block mail domain " + 
		
customer.getCurrentContactInformation().getPartyEmailAddress().getEmailLowercase()); 
		
		RejectionResult rejection = new OrderRejectionResult( );
		rejection.setMessage("BL: Block mail domain " + 
		
customer.getCurrentContactInformation().getPartyEmailAddress().getEmailLowercase());
		
		insert( rejection  );
		
end


And fragment of the code I'm using to compile rule package is:

		Reader testSource = new
InputStreamReader(RuleCompiler.class.getResourceAsStream("/perthTestRule.drl"));
		Reader sourceFlow = new
InputStreamReader(RuleCompiler.class.getResourceAsStream("/perthScoreCustomerFlow.rf"));

		// add the package to a rulebase (deploy the rule package).
		KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
		KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

		kbuilder.add(ResourceFactory.newReaderResource(testSource),
ResourceType.DRL);
		kbuilder.add(ResourceFactory.newReaderResource(sourceFlow),
ResourceType.DRF);

		System.out.println(kbuilder.getErrors().toString());

		Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages();

		try {
			kbase.addKnowledgePackages(pkgs);

			StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

			System.out.println("Knowladge session initialized...");
		} catch (Exception e) {
			e.printStackTrace();
		}
