----------------------------------------
Summary: ggregateReifier.mandatoryLookup fails during export
dry-run even with lazyBean=true
Key: CAMEL-23730
URL: https://issues.apache.org/jira/browse/CAMEL-23730
Project: Camel
Issue Type: Bug
Components: camel-sql
Affects Versions: 4.20.0
Reporter: Federico Mariani
When exporting a route that uses an aggregationRepository bean reference (e.g.,
#event_aggregation), the export dry-run fails with NoSuchBeanException even
though lazyBean=true is set by ExportBaseCommand.runSilently().
The issue is in AggregateReifier.createAggregationRepository() which calls
mandatoryLookup() to resolve the bean reference. This lookup is not lazy-aware
and throws immediately if the bean is not in the registry. During the export
dry-run, beans registered by ContextServicePlugin implementations may not be
available (e.g., because they require a live database connection or transaction
manager).
Other reifiers that use mandatoryLookup for bean references (e.g.,
idempotentRepository) may have the same issue.

org.apache.camel.FailedToCreateRouteException: Failed to create route:
event-batching
...
Caused by: org.apache.camel.NoSuchBeanException: No bean could be found in the
registry
for: #event_aggregation of type: org.apache.camel.spi.AggregationRepository
at
org.apache.camel.reifier.AbstractReifier.mandatoryLookup(AbstractReifier.java:178)
at
org.apache.camel.reifier.AggregateReifier.createAggregationRepository(AggregateReifier.java:247)
{code}
Expected behavior: When lazyBean=true (as set during camel export), bean
references in aggregationRepository should be resolved lazily or the lookup
failure should be treated as non-fatal, allowing the export to complete. The
exported application resolves the bean correctly at runtime.
Most probably, introduced by: The change from main.setStubPattern("*") to
main.setStubPattern("component:*") in the exportRun block of Run.java, related
to CAMEL-23355 / PR #22719 (or the referenced PR #21931).
Root cause: In 4.18, setStubPattern("*") stubbed ALL lookups including bean
references like #event_aggregation. In 4.20, setStubPattern("component:*") only
stubs component URIs. Bean references resolved via mandatoryLookup in reifiers
(e.g., AggregateReifier, IdempotentConsumerReifier) now fail with
NoSuchBeanException during the export dry-run when the bean is registered by a
ContextServicePlugin that requires runtime resources (database, transaction
manager).
