Попытка выполнить ./gradlew clean build для проекта, который использует gradle-3.5 .

Вывод версии Java;

 fuat@fuatk ~$ java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-0ubuntu1~20.04-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)
 

К сожалению, gradle IntegrationTest завершается с ошибкой;

 Connect to localhost:8080 [localhost/173.231.189.26] failed: Connection timed out (Connection timed out)
  org.apache.http.conn.HttpHostConnectException: Connect to localhost:8080 [localhost/173.231.189.26] failed: Connection timed out (Connection timed out)
 

И проверьте порты;

 fuat@fuatk ~$ netstat -antlp  | grep 8080
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp6       0      0 :::8080                 :::*                    LISTEN      1951584/java

При проверке PID

И тестовый класс;

 @RunWith(MockitoJUnitRunner.class)
public class PublicHolidayServiceGatewayTest {

    @Rule
    public final WireMockRule wireMockRule = new WireMockRule();

    @Mock
    private Configuration configuration;

    @Before
    public void setup() {
        final Collaborator collaborator = new Collaborator();
        collaborator.setUri("http://localhost:8080");
        when(configuration.getCollaborator()).thenReturn(collaborator);
    }

    @Test
    public void calculateWorkadaysShouldReturnWorkDaysCount_WhenServiceCallSucceeded() {

        final LocalDate from = LocalDate.of(2018, Month.SEPTEMBER, 29);
        final LocalDate to = LocalDate.of(2018, Month.NOVEMBER, 5);
        final String responseBody = "{"count":69}";

        stubFor(get(urlMatching("/publicholidays/2018-09-29/2018-11-05"))
                .willReturn(aResponse())
                        .withStatus(200).withBody(responseBody)));

        final PublicHolidayService publicHolidayService = new PublicHolidayServiceGateway(new DefaultAsyncHttpClient(), configuration);

        final Either<GatewayException, WorkDaysCountDto> workDaysCountDto = publicHolidayService.calculateWorkDays(from, to);

        assertThat(workDaysCountDto.isLeft(), is(Boolean.FALSE));
    }
}
 

Использование Wiremock 2.1.6 amp; Junit 4.12 .

Также вывод файла hosts;

 fuat@fuatk ~$ cat /etc/hosts
127.0.0.1   localhost
127.0.1.1   fuatk

18.213.137.78   registry-1.docker.io

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
 

Вопрос в том, почему я это вижу Connect to localhost:8080 [localhost/173.231.189.26] failed ?

Разве это не должно быть похоже Connect to localhost:8080 [localhost/127.0.0.1] failed ?
