Maven coordinates

Create a new project with this extension on code.quarkus.io

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-grpc</artifactId>
</dependency>

Check the User guide for more information about writing Camel Quarkus applications.

Camel Quarkus limitations

Integration with Quarkus gRPC is not supported

At present there is no support for integrating Camel Quarkus gRPC with Quarkus gRPC. If you have both the camel-quarkus-grpc and quarkus-grpc extension dependency on the classpath, you are likely to encounter problems at build time when compiling your application.

Protobuf generated code

You can generate gRPC service stubs with protobuf. A limitation of this is that generated code is annotated with the non Jakarta EE 10 friendly @javax.annotation.Generated.

To avoid compilation issues, the grpc-java project recommendation is to add a provided scoped dependency like this:

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>annotations-api</artifactId>
    <version>6.0.53</version>
    <scope>provided</scope>
</dependency>

Alternatively, you can use Maven or Gradle plugins to iterate over the generated code (found at target/generated-sources for Maven) and replace all instances of @javax.annotation.Generated with @jakarta.annotation.Generated.
