How can a private repository be built using Nexus3?

To set up a private repository, Sonatype Nexus can be used. Here is a guide on how to build a private repository using Nexus 3.

1. Download and install Nexus 3: Download the latest version of Nexus 3 from the official Sonatype website and follow the official documentation for installation.
2. Start up Nexus 3: Launch Nexus 3 by running the bin/nexus script in the Nexus 3 installation directory, or use the system service to start Nexus 3.
3. Access the management console: Access http://localhost:8081/nexus in your browser and log in to the Nexus management console using the default admin username and password (admin/admin123).
4. To create a new repository, go to the management console, click on the “Repositories” option in the left sidebar, and then click on the “Create repository” button in the top right corner. Choose the type of repository that suits your needs, such as Maven, npm, Docker, etc., and follow the instructions to fill in the necessary information to create a new repository.
5. Set up warehouse access permissions: In the management console, click on the “Security” option in the left navigation bar, then click on “Realms.” Choose the appropriate authorization policy, and create users and roles as needed to control access to the warehouse.
6. Deploying and utilizing private repositories: By deploying your project build output to a Nexus repository, you can use the corresponding build tool’s plugins or command-line tools to achieve this. Specify the URL of the private repository in the project’s configuration files so that other developers can fetch dependencies from the private repository.
7. Updating and managing private repositories: In the management console, you can manage components and versions in the repository, including uploading new versions, deleting old versions, and managing metadata.

The above is a basic method for setting up a private repository using Nexus 3. The specific details may vary depending on your individual needs and environment. Refer to the official Nexus documentation for more detailed information and guidance.
