Unable to set date format by on RHDM using -Ddrools.dateformat=yyyy-MM-dd

Solution Verified - Updated -


I 'm trying to change date format in rules by starting EAP with -Ddrools.dateformat=yyyy-MM-dd. But the following logs are still shown during startup,

2019-06-04 10:18:37,948 INFO  [org.guvnor.common.services.backend.config.DefaultApplicationPreferencesLoader] (MSC service thread 1-5) Setting preference 'drools.dateformat' to 'dd-MMM-yyyy'.

and build of rules fails like the following

2019-06-04 10:19:00,556 ERROR [org.drools.compiler.kie.builder.impl.KieProject] (EJB default - 1) Unable to build KieBaseModel:DefaultKieBase
Unable to Analyse Expression date < "1-May-2019":
[Error: Comparison operation requires compatible types. Found class java.util.Date and class java.lang.String]
[Near : {... date < "1-May-2019" ....}]
                    ^ : [Rule name='Rule']

Wrong date-effective value: Invalid date input format: [1-May-2019] it should follow: [yyyy-MM-dd] : [Rule name='Rule1']

What is a correct way to change drools.dateformat?
