Receiver - Can't handle model of type ReceiverModel with tag: receiver

[raymondsvendsen]

Attempting Logback receiver feature I get this error:
ERROR in ch.qos.logback.core.model.processor.DefaultProcessor@76b10754 - Can't handle model of type class ch.qos.logback.classic.model.ReceiverModel with tag: receiver at line 11

My setup:

• Arch Linux 6.5.5 kernel
• Logback 1.3.11 (also tried other versions, including 1.4.x. 1.3 is prefered since I am stuck with java 8 in prod)
• SLF4J 2.0.9 (also tried 2.0.7)
• Java 8,11,17 all give same result
• Also tried run application in a docker-container to rule out my environment ( maven:3.5-jdk-8)

To reproduce:
Structure:

Main.java:

package logbackreceiver.server;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Main {
  private static final Logger logger = LoggerFactory.getLogger(Main.class);
  static public void main(String[] args) {
    logger.info("Starting");
  }
}

logback.xml:
(I also tried the canonical style with same result)

<configuration debug="true">

To build and run:

mvn clean compile && sudo mvn exec:java -Dexec.mainClass="logbackreceiver.server.Main"

Following the guide here: https://logback.qos.ch/manual/receivers.html
I also cloned code from github (various versions here too) and run the example codes. Everything give me the same problem.
I tried various versions of Logback (3.x and 4.x). I tried Java 8,11,17
I would prefer to make Logback 3.x to work since I am stuck with Java 8 in prod.

I even tried run it in a Docker-container to rule out problems in my environment.

I would be happy to know if this should work. Does no one use this feature?

[VolkerGoetz]

I have the very same error and opened a ticket in the old Jira tracker: https://jira.qos.ch/browse/LOGBACK-1743

PR #699 has a fix for this.

[raymondsvendsen]

Thank you for the information.

[meyertee]

I ran into the same issue, thanks for the PR. Would be great to get an update on whether that's considered for merging into an upcoming release. Was there a reason not to support the receiver tag or just an oversight/bug?

[jhartelt]

Also encountered this issue. Until a new release is available, would I have to build the logback-classic.jar myself to fix this behaviour?

@ceki Any chances of addressing the issue in the near future? The bug basically makes the receiver functionality unusable but the PR posted above is a straightforward fix.
