Running
./gradlew clean build && java -jar micronaut-camunda-bpm-example/build/libs/micronaut-camunda-bpm-example-0.0.1-SNAPSHOT-all.jar will not determine the Netty Version but logs
WARN i.n.m.c.b.f.MnTelemetryRegistry - Unable to identify the application server for the telemetry data!

Notes

• it works when started in IntelliJ
• it doesn't work in the fat jar created by the shadow plugin
• Version.identify() only returns {netty-codec-http2=netty-codec-http2-4.1.58.Final.10b03e6}

This also fails for docker which uses the fat-jar:

1. Save micronaut-camunda-bpm-example/Dockerfile:

FROM openjdk:14-alpine
COPY build/libs/micronaut-camunda-bpm-example-*-all.jar app.jar
EXPOSE 8080
CMD ["java", "-Dcom.sun.management.jmxremote", "-Xmx128m", "-jar", "app.jar"]

2. execute

cd micronaut-camunda-bpm-example
docker build --tag myapp .
docker run myapp
