Geoffrey De Smet resolved JBRULES-2043.
---------------------------------------
Fix Version/s: 5.0.0.GA
Resolution: Done
If you mean your scoreDrl didn't point to a correct classpath resource,
I've tested that out on the latest version and now you get a decent message:
Exception in thread "main" java.lang.IllegalArgumentException: scoreDrl
(/org/drools/solver/examples/travelingtournament/solver/smart/ggsmartTravelingTournamentScoreRules.drl)
does not exist as a classpath resource.

Dietmar Scheidl reopened JBRULES-2043:
--------------------------------------
There is a scoreDrl file but the problem is an error in the rules. As a result the
PackageBuilder reads the drl file and can not compile it.
When you directly use Drools you can use PackageBuilder::getErrors() to get a clue whats
wrong in your rules. There is no check if building the scoreDrl failed with an error. If
so, it only throws the NullPointerException but does not show the PackageBuilderErrors.

Dietmar Scheidl commented on JBRULES-2043:
------------------------------------------
In org.drools.solver.config.localsearch.LocalSearchSolverConfig::buildRuleBase() fails:
private RuleBase buildRuleBase() {
...
RuleBaseConfiguration ruleBaseConfiguration = new RuleBaseConfiguration();
RuleBase ruleBase = RuleBaseFactory.newRuleBase(ruleBaseConfiguration);
try {
ruleBase.addPackage(packageBuilder.getPackage());
} catch (Exception e) { // TODO remove me if removed in drools 4.0.1
throw new IllegalArgumentException("scoreDrlList (" + scoreDrlList +
") could not be loaded.", e);
}
...
return ruleBase;
}
The thrown exception does not allow the analysis of the real problem.
In my case packageBuilder.getPackage() fails caused by a error in the rule-file. So
packageBuilder.getErrors() would return the list of problems.

Geoffrey De Smet commented on JBRULES-2043:
-------------------------------------------
Good point, looks like this thing has become obsolete:
} catch (Exception e) {
Instead I should do something like
if (packageBuilder.hasErrors()) {
// throw a runtime exception with mentions at least one of the errors
Logging all errors might seem like a good idea, but I should definition throw an exception
up the stack I think.

Geoffrey De Smet commented on JBRULES-2043:
-------------------------------------------
I've done this for now, but that doesn't mention which file caused the error, but
it does mention the line in that unknown drl :)
if (packageBuilder.hasErrors()) {
throw new IllegalStateException("There are errors in the
scoreDrl's:"
+ packageBuilder.getErrors().toString());
}
The real solution is that drools itself fails fast if we don't bother checking the
hasError method, see linked issue.

New subject: [JBoss JIRA] Updated: (JBRULES-2043) No decent error message when the scoreDrl doesn't exist (was: Log problems while building the RuleBase)

Geoffrey De Smet updated JBRULES-2043:
--------------------------------------
Fix Version/s: 5.2.0.M1
(was: 5.1.0.FINAL)
No decent error message when the scoreDrl doesn't exist (was: Log
problems while building the RuleBase)
-------------------------------------------------------------------------------------------------------
Key: JBRULES-2043
URL: https://jira.jboss.org/browse/JBRULES-2043
Project: Drools
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: drools-planner
Affects Versions: 5.0.0.M5
Reporter: Dietmar Scheidl
Assignee: Geoffrey De Smet
Fix For: 5.2.0.M1
I startet to experiment with the drools-solver but only got a NullPointerException:
Caused by: java.lang.NullPointerException
at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:429)
at org.drools.reteoo.ReteooRuleBase.addPackage(ReteooRuleBase.java:395)
at
org.drools.solver.config.localsearch.LocalSearchSolverConfig.buildRuleBase(LocalSearchSolverConfig.java:166)
at
org.drools.solver.config.localsearch.LocalSearchSolverConfig.buildSolver(LocalSearchSolverConfig.java:137)
at
org.drools.solver.config.XmlSolverConfigurer.buildSolver(XmlSolverConfigurer.java:73)
...
After debugging into this location, I found out that it comes from an error in my
scoreDrl.
The buildSolver-Method should fail with a more helpful exception or the result of the
PackageBuilder should be available to analyse the problems.
