-----------------------------------
Summary: 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
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.
