Description

Classpath file for Ozone components only include dependencies, but not the component's own jar file. Thus, Ozone needs to find it at runtime:

https://github.com/apache/ozone/blob/2139367b52d68773f25d79abce0439323dde9671/hadoop-ozone/dist/src/shell/ozone/ozone-functions.sh#L2820-L2826

  #We need to add the artifact manually as it's not part the generated classpath desciptor
  local MAIN_ARTIFACT
  MAIN_ARTIFACT=$(find "$HDDS_LIB_JARS_DIR" -name "${OZONE_RUN_ARTIFACT_NAME}-*.jar")
  if [[ -z "$MAIN_ARTIFACT" ]] || [[ ! -e "$MAIN_ARTIFACT" ]]; then
    echo "ERROR: Component jar file $MAIN_ARTIFACT is missing from ${HDDS_LIB_JARS_DIR}"
  fi
  ozone_add_classpath "${MAIN_ARTIFACT}"

This causes startup error if multiple versions of the same component happen to be present in the $HDDS_LIB_JARS_DIR directory.

It would be nice to add main artifacts to the classpath files at build time.
