Pom.xml dependency conflict resolver for multi-module Maven projects

The specific complaint is that 'managing the pom.xml becomes difficult with multiple dependency configurations' — and this isn't a complaint about Maven itself, it's a complaint about what happens at scale when you have five or ten modules with overlapping dependencies, version conflicts, and inherited settings that interact in ways nobody fully tracks.

The reason this persists is structural: Maven's dependency resolution happens at build time, but the decisions that cause conflicts are made incrementally over months as different developers add dependencies to different modules. By the time a conflict surfaces, the build history doesn't tell you who added what or why. There's no change history linked to the semantic meaning of the dependency graph — just a series of pom.xml commits that each looked reasonable in isolation.

What's actually missing is a diff tool that understands Maven's dependency resolution semantics — not just what changed in the XML, but what changed in the resolved dependency tree and whether those changes introduce version conflicts, unexpected transitive inclusions, or scope mismatches across modules. The 'too many technologies' complaint matters here too: in Apache projects that mix Java, Groovy, and FTL, pom.xml manages dependencies for all of them, and a conflict in a Groovy template library can surface as a cryptic Java classloading error that looks completely unrelated to the pom change that caused it.

This is a business because multi-module Maven projects with complex dependency graphs exist at virtually every company running Java at any meaningful scale, and the problem gets worse over time, not better — each new dependency added increases the surface area for future conflicts. The alternative is a dedicated DevOps engineer who does manual dependency audits, which costs far more than any tooling subscription.

What to build

Build a CI-integrated Maven plugin that runs on every pull request, computes the full resolved dependency tree before and after the change, and posts a diff comment showing newly added transitive dependencies, version changes, and scope conflicts across all modules — without requiring any changes to existing pom.xml files.

Where to start

Distribute as a free Maven plugin first, with the paid tier being the CI integration and historical trend view — the free plugin runs locally and immediately shows value, creating adoption before any sales conversation happens.

The hard part

The hardest first-customer problem is that dependency conflicts often only matter when they cause a production bug, not when the build succeeds — so teams don't feel the pain sharply enough to pay for prevention until they've already been burned badly, which means selling this requires either a freemium wedge or a very specific case study from a known incident.

How it makes money

Free Maven plugin with paid CI integration charged per repository per month (around $30–$80 depending on module count), with enterprise pricing for organizations running more than 20 active repositories.
