Three Strategies for Cross-Project Dependency Management in Maven: System Dependencies, Aggregator Modules, and Relative Path Modules
This article provides an in-depth exploration of three core approaches for managing cross-project dependencies in the Maven build system. When two independent projects (such as myWarProject and MyEjbProject) need to establish dependency relationships, developers face the challenge of implementing dependency management without altering existing project structures. The article first analyzes the solution of using system dependencies to directly reference local JAR files, detailing configuration methods, applicable scenarios, and potential limitations. It then systematically explains the approach of creating parent aggregator projects (with packaging type pom) to manage multiple submodules, including directory structure design, module declaration, and build order control. Finally, it introduces configuration techniques for using relative path modules when project directories are not directly related. Each method is accompanied by complete code examples and practical application recommendations, helping developers choose the most appropriate dependency management strategy based on specific project constraints.
