NullPointerException on running ./gradlew testIntegration

2020-06-17T18:22:31Z

Hi folks
I just created a service-builder module in liferay work space 7.2.1 and implement a test module for that.
when i execute ./gradlew testIntegration faced bellow error :

java.lang.NullPointerException

Here is my TaskLocalServiceTest:

@RunWith(Arquillian.class)
public class TaskLocalServiceTest {

&nbsp;&nbsp; &nbsp;@ClassRule
&nbsp;&nbsp; &nbsp;@Rule
&nbsp;&nbsp; &nbsp;public static final AggregateTestRule aggregateTestRule =
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;new LiferayIntegrationTestRule();&nbsp;&nbsp; &nbsp;@Before
&nbsp;&nbsp; &nbsp;public void setUp() throws Exception {
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;_group = GroupTestUtil.addGroup();
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;_user = TestPropsValues.getUser();&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;
         ServiceTestUtil.setUser(TestPropsValues.getUser());
&nbsp;&nbsp; &nbsp;}

&nbsp;&nbsp; &nbsp;@Test
&nbsp;&nbsp; &nbsp;public void testAddTask() throws Exception {
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;int initialCount = _taskLocalService.getTasksCount();
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;addTask(false);
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;int actualCount = _taskLocalService.getTasksCount();
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;Assert.assertEquals(initialCount + 1, actualCount);
&nbsp;&nbsp; &nbsp;}

&nbsp;&nbsp; &nbsp;protected Task addTask(boolean completed) throws Exception {
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return addTask(_user.getUserId(), completed);
&nbsp;&nbsp; &nbsp;}

&nbsp;&nbsp; &nbsp;protected Task addTask(long userId, boolean completed) throws Exception {
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;ServiceContext serviceContext =
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;ServiceContextTestUtil.getServiceContext(
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;_group.getGroupId(), userId);
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;Calendar dueDate = CalendarFactoryUtil.getCalendar(2020, 1, 1);
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return _taskLocalService.addTask(
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;userId, RandomTestUtil.randomString(),
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;RandomTestUtil.randomString(), completed, dueDate.getTime(),
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;serviceContext);
&nbsp;&nbsp; &nbsp;}

&nbsp;&nbsp; &nbsp;@DeleteAfterTestRun
&nbsp;&nbsp; &nbsp;private Group _group;&nbsp;&nbsp; &nbsp;@Inject
&nbsp;&nbsp; &nbsp;private TaskLocalService _taskLocalService;
&nbsp;&nbsp; &nbsp;private User _user;

}

Also i have bellow @Component in my TaskLocalServiceImpl :

@Component(
&nbsp;&nbsp; &nbsp;property = "model.class.name=com.chberndt.liferay.todo.list.model.Task",
&nbsp;&nbsp; &nbsp;service = AopService.class
)
