Failed to collect dependencies of deployment artifact ${depl

Error message

Failed to collect dependencies of deployment artifact ${deploymentCoords}

What it means

The mojo collects the transitive dependency tree of the extension's deployment artifact via repoSystem.collectDependencies using the deployment artifact coords. Exceptions are wrapped as 'Failed to collect dependencies of deployment artifact <coords>'.

Solutions

1. Run mvn install on the deployment module (or full reactor build) before the runtime descriptor goal
2. Verify the deployment artifact exists in the local/remote repositories at the printed coords
3. Run with -U to refresh snapshot metadata
4. Inspect the wrapped cause for invalid-pom or network errors and fix accordingly

Example fix

# before: deployment artifact not installed
mvn package -pl my-ext
# after
mvn install -pl my-ext,my-ext-deployment

mvn dependency:get -Dartifact=my.org:my-ext-deployment:1.0.0

When it happens

Trigger: Deployment artifact coordinates cannot be collected: the deployment artifact doesn't exist in any repository, its POM is invalid, or repository access fails when getCollectedDeploymentDeps() first runs.

Common situations: Deployment module not built/installed before the runtime module's descriptor goal; missing repo hosting the deployment artifact; invalid deployment pom; stale snapshot metadata.
