How to use MinIO SDK for java with Clojure

In this receipe we will learn how to use minio-java with Clojure.

Prerequisites

Install Clojure and Leiningen.

Check by running -

lein --help

Clojure Project

Following are the steps involved foe using minio-java with Clojure:

1. Setup

Create a new Clojure project using Leiningen.

lein new <templateName> <projectName>

Example:

lein new app clojproject

Navigate to project.clj look at :dependencies section, consisting of dependencies that project requires in order to load, compile and run.

lein deps

Run this command to install list of dependencies to your project.

Use Leiningen to start Clojure now -

lein repl

Test the project by running (-main).

user=> (-main)
Hello, World!
nil

Or you can run the project using command - lein run.

2. Download minio-java from maven

Go to maven and search minio. Download the lastest version and add dependency in the project.clj.

::dependencies [
                [io.minio/minio "4.0.2"]
               ]

Run lein deps.

Check lein classpath to see if minio.jar is present.

/.m2/repository/io/minio/minio/4.0.2/minio-4.0.2.jar

Relaunch repl for Clojure and use minio-java.

3. Test

Use classes and methods from the imported class in your project.

(ns clojproject.core
 (import io.minio.MinioClient)
)

(defn -main
  [& args]
    ;; makeBucket
    (.makeBucket (new io.minio.MinioClient "https://play.min.io:9000" "Q3AM3UQ867SPQQA43P2F" "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG") "testbucketclojure")

    ;;putObject
    (.putObject (new io.minio.MinioClient "https://play.min.io:9000" "Q3AM3UQ867SPQQA43P2F" "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG") "testbucketclojure"  "objectname" "/Users/aarushiarya/Desktop/testFile")
    (println "Done.")
    )
