无法识别PowerMockRunner，但所有依赖项都已到位

Question

在我的单元测试中，powermockrunner尚未确认，尽管我在pom中需要所有依赖项，并且都下载了所有必需的罐子。我正在尝试测试一种静态方法。我不断获得错误"Type mismatch: cannot convert from Class<PowerMockRunner> to Class<? extends Runner>" @RunWith(PowerMockRunner.class)。为什么现在已经认可PowerMockrunner？我很确定我所有的依赖项都已添加。我正在使用junit4。这是我的pom文件：

注意：这不是重复的帖子。我的问题承认，为了运行PowerMock，需要某些依赖性，但是这个特定的问题问，为什么在添加了所有这些依赖项后，PowerMockrunner.Class仍然无法识别。

这是我的简单测试：

@RunWith(PowerMockRunner.class)
@PrepareForTest(UserDAO.class)
public class UserDAOTest {
    @Test
    public void createShouldReturnUserId() {
        UserDAO dao = new UserDAO();
        PowerMockito.mockStatic(UserDAO.class);
        when(IDGenerator.generateId()).thenReturn(1);
        int result = dao.create(new User());
        assertEquals(1, result);
    }
}

尝试添加powermock-module-junit4-common

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-module-junit4-common</artifactId>
    <version>1.6.4</version>
</dependency>
