ambiguity with 'end' keyword and end() method in drl file

[kartheektr...@gmail.com]

Hi,

I have written a rule below which will be triggered when it finds an email id in the text, but when I am executing this getting the below error which is due to the method call matcher.end().

Drools is finding it as end keyword and throwing the exception

Please suggest me on rectifying this

: Error while creating KieBase[Message [id=1, level=ERROR, path=../../../emailaddress.drl, line=22, column=0

   text=[ERR 107] Line 22:95 mismatched input '(' expecting one of the following tokens: '[package, import, global, declare, function, rule, query]'.], Message [id=2, level=ERROR, path=../../../emailaddress.drl, line=0, column=0

   text=Parser returned a null Package]]

RULE:

rule "emailaddress rules"

 dialect "java"

    when

          $emailAddress :String(this matches "^.*[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,}).*$")

    then

    System.out.println("Rule 1-Triggered");

    Pattern pattern=Pattern.compile("[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})");

    Matcher matcher=pattern.matcher($emailAddress);

    while(matcher.find()){

    System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.");

    System.out.println("Email address is:"+$emailAddress.substring(matcher.start(),matcher.end()));

    }

        System.out.println("Rule Executed successfully");

end

Thanks for reporting this. We will look into it. Meanwhile, can you
please open a JIRA ticket for it in order to track it?

Thank you,
Edson

Hi,

I reported this issue here https://issues.jboss.org/browse/DROOLS-889 and fixed it on master with this commit https://github.com/droolsjbpm/drools/commit/49fdcf94b

As a temporary workaround for your problem I suggest you to put the code snippet invoking that end() method in another static java method and calling this second one from the rule's consequence.

Cheers,

Mario
