从org.glassfish.jersey.test.JerseyTest@test（groups={“integration”}）到TestNG的NPE

我有一个gradle项目，它引入了Jersey 2.13，通过TestNG进行测试，并利用Jersey测试框架。通过@test注释作为普通单元测试运行的任何测试都可以正常运行。如果我试图通过@Test（groups={“integration”}）将Jersey测试放入TestNG组中，测试将失败，NPE来自org.glassfish.Jersey.Test.JerseyTest。未利用Jersey测试框架的测试在@Test（groups={“integration”}）中正确执行时不会出现此问题。知道为什么TestNG在组约束下不能正确启动这个容器吗

这是项目的执行部分

test {
    useTestNG() { excludeGroups 'integration' }
}

task integrationTest(type: Test, dependsOn: 'test') {
    useTestNG() { includeGroups 'integration' }
}

失败的集成测试

public class JerseyTestNGTest extends JerseyTestNg.ContainerPerClassTest {
  @Path("hello")
  public static class HelloResource {
    @GET
    public String getHello() { return "Hello World!"; }
  }

  @Override
  protected Application configure() {
    return new ResourceConfig(HelloResource.class);
  }

  @Test
  public void notIntegrationTest() {
    // works like a champ...
    doIt();
  }

  @Test(groups = {"integration"})
  public void integrationTest() {
    // NPEs out the wazoo
    doIt();
  }

  private void doIt() {
    final String hello = target("hello").request().get(String.class);
    assertEquals("Hello World!", hello);
  }
}

眼泪的痕迹

...

怎么回事

整个项目都在github上，如果您有兴趣看到它运行，或者失败（视情况而定）：

Crickets？有人使用Jersey测试框架吗？也许这就是我犯错误的地方。无论如何，这感觉像是一个JerseyTest bug，所以我提出了一个问题：我有同样的问题，但是使用maven。这似乎真的是一个bug。当我从命令行用测试运行我的jar时，我也遇到了同样的问题。当我从eclipse运行时：没问题。。。我不使用gradle或maven
