I have a couple of rules and want them to run only one time in an agenda
group. When I called update in a rule, all rules will be re-match. How can I
let each rule in an agenda group run only one time?

you may check drools experts online documents section 5.8.1, Rule Attributes
like no-loop or activation-group or agenda-group.

I am using agenda group and put no-loop in each rule. But the problem is that
when one rule update the rule fact, other matched rules will be fired.
no-loop will prevent fire in one rule itself not for a whole agenda group.

when I put lock-on-active, the rule will never fire if there is only one
agenda group in a stateful session.

Strange... Does the rule at least get activated? I have used lock-on-active
before and it worked as expected. At that time I was not using any explicit
agenda group, so I also had just 1 agenda group.

I just tried and please look at my rule file. It is very simple, after fired
the session, this rule is not fired. I am using drools 5.1.1 and
statefulsession. Could you please provide your rule file to have a look at?
rule "add2"
agenda-group "add"
dialect "java"
lock-on-active
when
eval(true)
then
System.out.println("add2");
end

Are you activating the "add" agenda-group before the fireAllRules() call?

As soon as you use agenda-group "x" you have two groups: "MAIN" and
"x".

Yes, I have set focus on the agenda "add". I can see the push and pop event
in my listener.

The correct sequence is
insert facts (amd observe activations)
call setFocus( "add" )
call fireAllrules()

This is my code:
session.getAgenda().getAgendaGroup("add").setFocus();
try {
int rule=session.fireAllRules();
System.out.println(rule+" rules fired");
} catch (Exception e) {
e.printStackTrace();
}
The rule doesn't print the message and the code print "0 rules fired". I am
using drools 5.1.1. Is this the version you are using?
My rule file is:
rule "add2"
agenda-group "add"
dialect "java"
lock-on-active
when
eval(true)
then
System.out.println("add2");
end
