如何使用PowerMock & Mockito模拟枚举类的实例？

我试图遵循这个非常相似的问题的答案中提供的示例，但它对我不起作用。我得到以下错误消息：
java.lang.IllegalArgumentException: Cannot subclass final class class com.myproject.test.support.ExampleEnumerable

at org.powermock.api.mockito.internal.mockcreation.MockCreator.mock(MockCreator.java:58)
at org.powermock.api.mockito.PowerMockito.mock(PowerMockito.java:143)我需要一个简单的enum class模拟实例。我不需要模仿它的任何方法。
下面是我想模拟的类：
public enum ExampleEnumerable implements IEnumerable<ExampleEnumerable> {
EXAMPLE_ENUM_1("Test Enum 1"),
EXAMPLE_ENUM_2("Test Enum 2");
final String alias;
ExampleEnumerable(final String alias) {
this.alias = alias;
}
@SuppressWarnings({"VariableArgumentMethod", "unchecked"})
@Override
public @Nullable
String getAlias(final @Nonnull IEnumerable<? extends Enum<?>>... context) {
return alias;
}
}我有以下TestNG设置：
import static org.powermock.api.mockito.PowerMockito.mock;
@PrepareForTest({ ExampleEnumerable.class})
@Test(groups = {"LoadableBuilderTestGroup"})
public class LoadableBuilderTest {
private ExampleEnumerable mockEnumerable;
@BeforeMethod
public void setUp() {
mockEnumerable = mock(ExampleEnumerable.class);
}

我通过扩展为TestNG处理这类事情的PowerMockTestCase类实现了这一点：
@PrepareForTest(TestEnumerable.class)
@Test(groups = {"LoadableBuilderTestGroup"})
public class LoadableBuilderTest extends PowerMockTestCase {
private TestEnumerable mockEnumerable;
@SuppressWarnings("unchecked")
@BeforeMethod
public void setUp() {
mockEnumerable = PowerMockito.mock(TestEnumerable.class);
}

您需要使用PowerMockRunner运行此命令
例如：
@RunWith(PowerMockRunner.class)
@PrepareForTest({ ExampleEnumerable.class})
@Test(groups = {"LoadableBuilderTestGroup"})
public class LoadableBuilderTest {
private ExampleEnumerable mockEnumerable;
@BeforeMethod
public void setUp() {
mockEnumerable = mock(ExampleEnumerable.class);
}

大家好，对我来说是这样的：
首先在pom.xml上添加power模拟：
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>2.0.4</version>
<scope>test</scope>
</dependency>，然后是我的类：
@RunWith(PowerMockRunner.class)
@PrepareForTest({EnumClass.class})
public class EnumClassTest{
private EnumClassTest enumClassTest;
@Before
public void setUp() {
enumClassTest = mock(EnumClassTest.class);
}
@Test
public void someMethod() {
//My code test here
