Version cannot be determined on fat-jar

[tobiasschaefer]

To reproduce:

./gradlew clean build
java -jar micronaut-camunda-bpm-example/build/libs/micronaut-camunda-bpm-example-0.0.1-SNAPSHOT-all.jar

doesn't output the version:
INFO i.n.m.c.b.f.ProcessEngineFactory - Camunda BPM version:

This is also problematic because the telemetry data will be rejected by the Camunda telemetry endpoint if the version is missing. Therefore we currently need to disable the Telemetry Reporter in this case.

This also applies to 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

docker build --tag myapp .
docker run myapp

Note:

• This only happens if camunda.bpm.generic-properties.properties.initialize-telemetry is explicitly set to true
• if the dependency is pulled into a project and the application is started from IntelliJ, everything is fine.
• the information seems to get lost with the repackaging of the shadow jar plugin
• The Camunda Cockpit actually shows the version number in the footer also in case of a shadow jar. Where does it come from? Is this version somewhere in the UI?
