Description

When trying to export a project using the export feature, the resulting project does not compile due to the following error (see build.log attachment for details).

Step 1: export the project
camel export --dependency=dev.langchain4j:langchain4j-core:0.33.0 --dependency=dev.langchain4j:langchain4j-open-ai:0.33.0 --runtime=quarkus Weather.java

Step 2: try to build the generated project
mvn verify

Result:
Compilation fails with the following error:

[error]: Build step io.quarkiverse.langchain4j.deployment.BeansProcessor#handleProviders threw an exception: io.quarkus.runtime.configuration.ConfigurationException: A ChatLanguageModel or StreamingChatLanguageModel bean was requested, but no langchain4j providers were configured. Consider adding an extension like 'quarkus-langchain4j-openai'

The problem is that the generated project should be using io.quarkiverse.langchain4j:quarkus-langchain4j-core:0.16.4 and io.quarkiverse.langchain4j:quarkus-langchain4j-openai:0.16.4 instead.

Adjusting the pom.xml file to manually replace the dependencies solve the problem.
