Claus Ibsen resolved CAMEL-24822.
---------------------------------
Resolution: Fixed
> camel run: rest-openapi producer fails with a null Vert.x unless
> componentName=http is set
> ------------------------------------------------------------------------------------------
>
> Key: CAMEL-24822
> URL: https://issues.apache.org/jira/browse/CAMEL-24822
> Project: Camel
> Issue Type: Improvement
> Components: camel-jbang, camel-rest-openapi
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 4.23.0
>
>
> Found while writing the openapi-client example for CAMEL-24808.
> A YAML route with
> {code}
> - to:
> uri: rest-openapi
> parameters:
> specificationUri: stock-api.json
> operationId: reserveStock
> host: http://localhost:8080
> {code}
> run with *camel run* fails at startup with:
> {noformat}
> Failed to start route ... because: java.lang.NullPointerException: Cannot
> invoke
> "io.vertx.core.Vertx.createHttpClient(io.vertx.core.http.HttpClientOptions)"
> because "vertx" is null
> {noformat}
> The component defaults to the vertx-http client, but camel-jbang's dependency
> detection adds camel-rest-openapi only, not camel-vertx-http, so the default
> client has no Vert.x. Setting *componentName: http* works because camel-http
> is then detected from the option value.
> Proposal: when rest-openapi is used as a producer, add the default HTTP
> client's component to the dependencies (or default to camel-http under camel
> run), and make the error say which component to configure instead of an NPE.
