smongiar opened a new pull request, #27206:
URL: https://github.com/apache/camel/pull/27206
## Summary
- `ExportBaseCommand.resolveDependencies()`: add a defensive fallback that
reads `spec.dependencies` from every official kamelet used in the integration
and includes them in the export dependency set.
- `KameletCatalogHelper`: add `findKameletDependencies()` — loads the
catalog once and returns `Map<name, deps>`, reusing the same download as
`findKameletNames`.
- `known-third-party-libraries.properties`: add
`com.fasterxml.jackson.annotation → jackson-annotations` mapping.
## Root cause
`camel export` captures kamelet-declared dependencies through a download
listener that fires during the silent run. This mechanism requires the full
chain: Java route builder compiles → kamelet endpoint resolves → template loads
→ `DependencyDownloaderKamelet` fires → listener writes `dependency=` to
settings. If the Java route builder fails to compile (e.g., `jackson-databind`
not yet on the classpath) before the kamelet is reached, its
`spec.dependencies` are never written and are absent from the exported
`pom.xml`.
The JSON kamelet (`json-deserialize-action`) declares `camel:jackson` in
`spec.dependencies`, but the test's route builder imports `ObjectMapper` and
`@JsonProperty` directly. The compilation fails because Jackson is not
pre-downloaded, which in turn prevents the kamelet from loading and recording
its own `camel:jackson` dependency — a circular bootstrap problem.
## Fixes
**1. Fallback in `resolveDependencies()`** — after the main settings loop,
iterate over `kamelet=` entries and add their `spec.dependencies` from the
pre-loaded catalog map. This guarantees the dependency is present even when the
silent-run chain breaks.
**2. `known-third-party-libraries.properties`** — adds
`com.fasterxml.jackson.annotation =
com.fasterxml.jackson.core:jackson-annotations:${jackson2-version}` so
`JavaKnownImportsDownloader` pre-downloads `jackson-annotations` when a route
builder imports `@JsonProperty`, matching the existing `jackson-databind` entry.
## Test plan
- [ ] Existing `camel export` tests pass
- [ ] A kamelet integration that uses a Java route builder with direct
Jackson imports exports correctly without `--dep jackson`
- [ ] `camel export` for `json-deserialize-action` / `json-serialize-action`
kamelets succeeds
