Dependency required

Quarkus gRPC extension dependency

<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-grpc</artifactId>
</dependency>

you have generate-code goal of quarkus-maven-plugin enabled in your pom.xml. If you wish to generate code from different proto files for tests, also add the generate-code-tests goal:

<plugin>
        <groupId>io.quarkus</groupId>
        <artifactId>quarkus-maven-plugin</artifactId>
        <version>${quarkus-plugin.version}</version>
        <extensions>true</extensions>
        <executions>
          <execution>
            <goals>
              <goal>build</goal>
              <goal>generate-code</goal>
              <goal>generate-code-tests</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

To generate class from proto file

mvn compile

Important Note : Implementing a gRPC service

With Quarkus, implementing a service requires to extend the generated service base implementation and expose it as a @Singleton CDI bean. Don’t use @ApplicationScoped as the gRPC service implementation cannot be proxied.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/quarkus-protobuf-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.html.
