This has also forced plugins written in languages other than Groovy to use Groovy types for some APIs.

When the Kotlin DSL was introduced, we made an effort to add non-Groovy equivalents for all APIs.
This has been mostly done, but there remain a few holdouts (fixing these is out of scope).

To keep the Groovy DSL ergonomic, we generate methods as necessary from the non-Groovy equivalents.

Doing this provides the following specific benefits:

    echo \"Failed attempts: $ATTEMPTS\" ;
    if [ $ATTEMPTS -gt $LIMIT ]; then
      exit 1 ;
    fi ;
    sleep 2 ; # 1 second intervals between attempts
    $MC_COMMAND ;
    STATUS=$? ;
  done ;
  set -e ; # reset `e` as active
  return 0
}

# runCommand ($@)
# Run custom mc command
runCommand() {
  ${MC} "$@"
  return $?
}

# Try connecting to MinIO instance

You can use this template to get started, as it includes a lot of the initial set up, security, database and some API endpoints already done for you.
