How to do a local development?

[vutkin]

Hi @seglo ,

could you please advise how to do a local development?
Unfortunately I can't build local jar and run it:

rm -rf target
docker run -it \
  --rm \
  -v "$(shell pwd)":"/root" \
  sbtscala/scala-sbt:eclipse-temurin-17.0.4_1.7.1_3.2.0 \
  sh -c "sbt clean package"

but when I start jar it failed with error:

java -jar ./target/scala-2.12/kafka-lag-exporter_*.jar \
    -Dconfig.file=./application.conf \
Error: Unable to initialize main class com.lightbend.kafkalagexporter.MainApp
Caused by: java.lang.NoClassDefFoundError: com/typesafe/config/Config
make: *** [run] Error 1

Why is it too complicated to contribute?
