Training demos for Module 6 in Techworld with Nana bootcamp. Focusing on artifact repositories with Nexus.

Nexus Artifact Publisher

This project demonstrates setting up a private Nexus repository and publishing Java artifacts using both Gradle and Maven.

Source: Techworld with Nana bootcamp

🔧 Technologies Used

• Nexus
• DigitalOcean Droplet (Ubuntu)
• Java 17
• Gradle
• Maven
• Linux Shell Scripting

📦 Project Structure

• nexus-setup/ - Scripts and notes for installing/configuring Nexus
• gradle-project/ - Simple Java project built with Gradle, published to Nexus
• maven-project/ - Simple Java project built with Maven, published to Nexus

🚀 Steps Performed

1. Provisioned a DigitalOcean Droplet

• Ubuntu 24.10
• Opened necessary firewall ports:
  • 8081 for Nexus
  • 22 for SSH (only from specific IPs for security)

2. Installed and Configured Nexus

• Installed Nexus using commands listed in ( install-nexus.sh )
  • Commands were performed manually, although there is opportunity to automate if needed.
• Created a new user with proper permissions
  • System user named nexus was created for nexus tasks only
  • More details listed in ( configure-nexus.md )
• Used sample repository in Nexus (maven-snapshots)
• Note: This kind of repo is best for capturing builds for lower environments like Development/Test.

3. Created and Built Sample Java Projects

• One project using Gradle

• One project using Maven
  
  

  Note: Source files are from previous projects, provided by the author, Nana.

  • https://gitlab.com/twn-devops-bootcamp/latest/06-nexus/java-maven-app

4. Published Artifacts to Nexus

• Configured build.gradle and pom.xml to use Nexus as the repository
• Built JARs and pushed them using gradle publish and mvn deploy

5. Verified Uploads

• Logged into Nexus web UI
• Verified artifacts appeared in the correct repository

🔐 Notes

• Credentials are generally configured in ~/[insert_project_directory]/gradle.properties and ~/.m2/settings.xml (example templates included. see here for gradle and here for maven templates.)

📸 Screenshots

See /screenshots folder for proof of Nexus setup and successful artifact uploads.

🧠 Lessons Learned

• Nexus setup reinforced my knowledge about Linux permissions
• Understood how build tools publish to private artifact repositories
• Gained hands-on experience in setting up internal developer infrastructure
