>                 Key: DROOLS-3825
>                 URL: https://issues.jboss.org/browse/DROOLS-3825
>             Project: Drools
>          Issue Type: Bug
>            Reporter: Edoardo Vacchi
>            Assignee: Mario Fusco
>            Priority: Major
>              Labels: drools-core

> If you don't {{mvn clean}} each time you generate the executable model, new files will be generated at each run.
> These seem to be the culprit:
> {{PackageModel#getPackageUUID}}
> {code}
>     private String generateRulesFileName() {
>         return RULES_FILE_NAME + generateUUID();
>     }
> {code}
> solution: use a counter; the compiler is single-threaded, two runs produce the same output, existing files will be just overwritten
> deliverable: test case verifying files do not grow in number across runs
