Integrating Archiva with existing systems begins with connecting it to continuous integration tools like Jenkins or TeamCity, allowing automated deployments of build artifacts. Developers can configure their Maven or Gradle builds to publish directly to Archiva repositories. LDAP or Active Directory integration ensures secure and centralized user management. Archiva’s REST APIs allow further customization, letting it sync with issue tracking or project management tools. Establishing repository proxies to mirror external sources simplifies dependency management. Proper metadata organization and naming conventions are essential for maintaining consistent builds and smooth integration across systems.
