如何将Maven依赖项作为组进行管理？

Question

I got the following Maven module layout:

• All
  • Sub-Project 1
  • Sub-Project 2
  • Sub-Project 3
  • Sub-Project N
  • Deliverable-Build
  • Dependency-Report

I manage all my submodule versions in the 'All' as managed dependencies. I reference those managed dependencies in the 'Deliverable-Build' module, to include them in the final zip archive.

The same dependency set needs to be referenced in the 'Dependency Report' module.

If the developer creates a new sub-module. He needs to manually put the new module into

1. 'All' as managed dependency
2. 'Deliverable-Build' as dependency
3. 'Dependency-Report' as dependency

It is easy to forget one of those, so is there a way to simplify this? eg by once defining a 'dependency group' and reusing it in those three locations?

Answer 1

You cannot combine dependencyManagement and dependency lists into one whole. For no. 2 and 3, you could create a pom containing all relevant dependencies and reference it, as described in

How to use POMs as a dependency in Maven?

Let me add two comments:

1. Perhaps you can create your Dependency-Report in the Deliverable-Build project, so that you reduce the duplication of logic. Eg listing all dependencies is done by the Maven-Site-Plugin.
2. I would avoid to create too many modules.
