Is this progress? ... KieBase (drools 6) versus RuleBase (drools 4)

gistfile1.txt

Given List<String< scoreDrlList, how do we build a RuleBase/KieBase?

Drools 4 (building a RuleBase):

            PackageBuilder packageBuilder = new PackageBuilder();
            for (String scoreDrl : scoreDrlList) {
                InputStream scoreDrlIn = getClass().getResourceAsStream(scoreDrl);
                packageBuilder.addPackageFromDrl(new InputStreamReader(scoreDrlIn, "UTF-8"));
            }
            RuleBaseConfiguration ruleBaseConfiguration = new RuleBaseConfiguration();
            RuleBase ruleBase = RuleBaseFactory.newRuleBase(ruleBaseConfiguration);
            if (packageBuilder.hasErrors()) { ... }
            ruleBase.addPackage(packageBuilder.getPackage());
            return ruleBase;


Drools 6 (building a KieBase):


            KieServices kieServices = KieServices.Factory.get();
            KieResources kieResources = kieServices.getResources();
            KieFileSystem kieFileSystem = kieServices.newKieFileSystem();
            for (String scoreDrl : scoreDrlList) {
                InputStream scoreDrlIn = getClass().getResourceAsStream(scoreDrl);
                String path = "src/main/resources/optaplanner-kie-namespace/" + scoreDrl;
                kieFileSystem.write(path, kieResources.newInputStreamResource(scoreDrlIn, "UTF-8"));
            }
            KieBuilder kieBuilder = kieServices.newKieBuilder(kieFileSystem);
            kieBuilder.buildAll();
            Results results = kieBuilder.getResults();
            if (results.hasMessages(Message.Level.ERROR)) { ...
            } else if (results.hasMessages(Message.Level.WARNING)) { ... }
            KieContainer kieContainer = kieServices.newKieContainer(kieBuilder.getKieModule().getReleaseId());

            KieBaseConfiguration kieBaseConfiguration = kieServices.newKieBaseConfiguration();
            KieBase kieBase = kieContainer.newKieBase(kieBaseConfiguration);


Is this progress?

Note: like 90% of the users out there, I don't care about building multiple KieBases.
And if the api would following the principle of configuration by exception, I wouldn't need to care either...
