How to fix the error Caused by: java.net.BindException: Address already in use: bind in Quarkus?

Question

I've created a quarkus quick start project with

mvn io.quarkus:quarkus-maven-plugin:0.13.1:create \
    -DprojectGroupId=com.demo.quarkus \
    -DprojectArtifactId=quarkus-project \
    -DclassName="com.demo.quarkus.HelloResource" \
    -Dpath="/hello"

And afterwards when I run:

mvn clean package

I get the following error:

The origin of the error seems to be coming from

@QuarkusTest
public class HelloResourceTest {

    @Test
    public void testHelloEndpoint() {
        given()
                .when().get("/hello/filipe")
                .then()
                .statusCode(200)
                .body(is("hello"));
    }

}

I'm not sure which port it is trying to bind to. I suppose 8080.

Any ideas how to override the default port using the application.properties?

I'm on windows.

Thanks!

Answer 1

It seems that besides the normal HTTP port, there is also a default port used during tests. So in order to override the default port used in tests, the following property needs to be overridden:

quarkus.http.test-port=8888

This will run the rests using port 8888.

The answer for this question pointed me in the right direction: How can I configure the port a Quarkus application runs on?

As well as the comment pointing to https://github.com/quarkusio/quarkus/blob/0.14.0/extensions/undertow/runtime/src/main/java/io/quarkus/undertow/runtime/HttpConfig.java

More info here: https://quarkus.io/guides/getting-started-testing#controlling-the-test-port

Answer 2

It seems to use 8080 by default.

Quarkus itself is configured via the same mechanism as your application. Quarkus reserves the quarkus. namespace for its own configuration. For example to configure the HTTP server port you can set quarkus.http.port in application.properties.
