Artifactory: using Gradle and Uploading Artifacts to Artifactory

Step-by-Step Guide: Creating a Java Project with Gradle and Uploading Artifacts to Artifactory

1. Install Prerequisites

• Java JDK: Ensure Java (preferably JDK 17 or newer) is installed. Check with java -version.
• Gradle: Install Gradle (version 8+ recommended). Check with gradle -version.

2. Create a New Java Project Using Gradle

Open your terminal and execute:

textgradle init --type java-application

• Follow the interactive prompts to choose Java as the language and select other defaults as needed.
• This command will generate a new Gradle Java project with a standard directory structure1234.

Alternatively, you can manually create a folder, navigate into it, and execute gradle init to set up your project.

3. Build the Project

Navigate into your project folder (if not already there):

textcd your-project-name

Build and test your project:

textgradle build

You’ll find the generated JAR in build/libs folder.

4. Add Artifactory Publishing Support

a. Apply the Artifactory Plugin

Add the following to your build.gradle (Groovy DSL):

groovyplugins {
    id 'java'
    id 'maven-publish'
    id 'com.jfrog.artifactory' version '5.2.0' // Use the latest compatible version
}

b. Configure Artifactory Publishing

Add this to your build.gradle:

groovypublishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
    }
}

artifactory {
    contextUrl = 'https://artifactory.example.com/artifactory' // <-- your Artifactory URL
    publish {
        repository {
            repoKey = 'libs-release-local' // or your repository key
            username = findProperty('artifactory_user') ?: System.getenv('ARTIFACTORY_USER')
            password = findProperty('artifactory_password') ?: System.getenv('ARTIFACTORY_PASSWORD')
            maven = true
        }
        defaults {
            publications('mavenJava')
        }
    }
}

Important: Never hardcode credentials. Use Gradle properties files (~/.gradle/gradle.properties) or environment variables to provide artifactory_user and artifactory_password56.

c. Optional: Add Snapshots Repo

If you need to deploy snapshot versions, add a similar block for a snapshot repository with the appropriate repoKey.

5. Publish to Artifactory

Deploy your artifact to Artifactory by running:

textgradle artifactoryPublish

If everything is set up correctly, your artifact will be uploaded to the specified location in Artifactory76.

Summary Table

With these steps, you can create a new Java Gradle project and publish its build artifacts directly to your Artifactory server in a secure and repeatable manner1756.

Another Method

Here is a step-by-step guide to create a new Java project using Gradle and configure it to upload artifacts to JFrog Artifactory.

✅ 1️⃣ Install Prerequisites

• Java JDK (version 8+)
• Gradle (latest version recommended)
• Artifactory URL & credentials (from your DevOps/admin team)

Verify installation:

java -version
gradle -v

✅ 2️⃣ Create a New Gradle Java Project

Option A: Using Gradle CLI

gradle init --type java-application

Follow prompts:

• Project type: application
• Language: Java
• Build script DSL: Groovy or Kotlin

This will create:

build.gradle
settings.gradle
src/main/java
src/test/java

✅ 3️⃣ Configure build.gradle for Publishing

Open build.gradle and make the following changes:

🔹 Apply Required Plugins

plugins {
    id 'java'
    id 'maven-publish'
}
Code language: JavaScript (javascript)

🔹 Configure Group, Version & Artifact Name

group = 'com.example'
version = '1.0.0'
Code language: JavaScript (javascript)

🔹 Setup Artifactory Publishing

Add this to build.gradle:

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
            groupId = 'com.example'
            artifactId = 'my-artifact'
            version = '1.0.0'
        }
    }

    repositories {
        maven {
            url = uri("https://your-artifactory-domain/artifactory/libs-release-local")
            credentials {
                username = project.findProperty("artifactory_user") ?: "your-username"
                password = project.findProperty("artifactory_password") ?: "your-password"
            }
        }
    }
}
Code language: JavaScript (javascript)

✅ 4️⃣ Store Credentials Securely

Instead of hardcoding, use gradle.properties:

📂 ~/.gradle/gradle.properties

artifactory_user=admin
artifactory_password=your-api-key-or-password

✅ 5️⃣ Build the Artifact

Run:

gradle clean build

Output: JAR file inside build/libs/my-artifact-1.0.0.jar.

✅ 6️⃣ Publish to Artifactory

Run:

gradle publish

✅ This uploads the JAR to your Artifactory repository.

✅ 7️⃣ Verify Upload

• Open Artifactory web UI
• Navigate to your repository (libs-release-local)
• Confirm my-artifact-1.0.0.jar is uploaded.

✅ 8️⃣ (Optional) Use the JFrog Gradle Plugin

JFrog provides a dedicated plugin for advanced features like build-info and CI/CD integration.

Add to build.gradle:

plugins {
    id "com.jfrog.artifactory" version "5.2.0"
}
Code language: JavaScript (javascript)

Configure:

artifactory {
    contextUrl = "https://your-artifactory-domain/artifactory"
    publish {
        repository {
            repoKey = "libs-release-local"
            username = "${artifactory_user}"
            password = "${artifactory_password}"
        }
        defaults {
            publications('mavenJava')
        }
    }
}
Code language: JavaScript (javascript)

Publish:

gradle artifactoryPublish

📌 Summary

✅ You created a Java project using Gradle
✅ Configured it to upload artifacts to JFrog Artifactory
✅ Secured credentials with gradle.properties
✅ Used gradle publish to push JAR to Artifactory
