responds with HTTP 409 Conflict

The repository 'maven-snapshots' rejected the resolution of an artifact 'maven-snapshots:com/github/CloudburstMC/Protocol/6985f66/Protocol-6985f66.pom' due to conflict in the snapshot release handling policy.

A work-around is to give the Maven repo https://jitpack.io a higher priority than https://repo.opencollab.dev
