Junit 5 集成测试在 maven 3.5.2 构建中失败

Question

Junit5 integration runs standalone in intellij but fails in maven build with stacktrace as below.

Caused by: java.lang.IllegalAccessError: superinterface check failed: class eu.nets.domain.QueuedMessage$HibernateProxy$1spaQq7T (in module eu.nets.queue.domain) cannot access class org.hibernate.proxy.ProxyConfiguration (in unnamed module @0x72a21be8) because module eu.nets.queue.domain does not read unnamed module @0x72a21be8**

Please let me know if complete stacktrace is required

• tried with latest maven-surefire-plugin 3.0.0-M3
• ran with jdk11 as release

Here is the test:

@Test
void fetchMessagesViaAdapter() throws Exception {
    MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders
            .post("/resend")
            .content("[\"queue1\"]")
            .contentType(APPLICATION_JSON_UTF8_VALUE))
                                 .andExpect(status().isOk())
                                 .andReturn();
    String resultDOW = mvcResult.getResponse().getContentAsString();
    assertAll(
            () -> assertNotNull(resultDOW),
            () -> assertEquals("success", resultDOW));
}

Answer 1

module eu.nets.queue.domain does not read unnamed module

Based on the error that you get, you can add the following VM option to resolve this -

--add-reads eu.nets.queue.domain=ALL-UNNAMED
