Initial Install dependency problem

[brianmichalk1]

I installed in 2022, and played around with JRule, and put it away. I'm now wanting to try JRule again, but am having dependency issues.
I installed via the openhab extension manager:

did chmod 775 to the jrule directory for my user.
Created a short example in /etc/openhab/automation/jrule/rules/org/openhab/automation/jrule/rules/user/BkmTest.java

package org.openhab.automation.jrule.rules.user;

import static org.openhab.automation.jrule.generated.items.JRuleItemNames.shelly2;
import org.openhab.automation.jrule.rules.event.JRuleEvent;
import org.openhab.automation.jrule.rules.JRuleName;
import org.openhab.automation.jrule.rules.JRuleWhenItemChange;
import org.openhab.automation.jrule.rules.JRule;


public class BkmTest extends JRule { 
    @JRuleName("MyEventValueTest")
    @JRuleWhenItemReceivedCommand(item = shelly2)
    public void myEventValueTest(JRuleEvent event) {
        logInfo("Got value from event: {}", event.getState().getValue());
    }    
}

and get this error

I removed the package declaration, extracted the jars from jrule/jar/ and added those directories to my Java source path. I'm pretty sure it's a simpler fix than the things I've tried.

EDIT: Should I move this question over to the openhab.org thread?
EDIT2: I ignored the VSCode errors, and it compiles in the Openhab environment and deploys, but doesn't trigger.
