ExceptionInInitializerError with Mockito

问题

以下是您提供的代码的翻译：

我看到了很多类似的问题，但似乎没有一个能够解决这个问题。无论我尝试什么，我都不断收到 `ExceptionInInitializerError` 错误：

```java
import static org.junit.Assert.fail;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;

import org.mockito.MockitoAnnotations;
import org.mockito.runners.MockitoJUnitRunner;
import org.springframework.web.client.RestTemplate;    

import org.springframework.web.client.RestTemplate;


@RunWith(MockitoJUnitRunner.class)
public class ClassTest {

    @Mock
    private RestTemplate mockedRestTemplate;


    @Before
    public void setup() {
	    MockitoAnnotations.initMocks(this);
    }

    @Test
    public void test() {	
	    fail("Not IMMM");
    }

}

我还尝试过 @RunWith(SpringRunner.class)，但仍然出现相同的错误。

堆栈跟踪如下：

java.lang.ExceptionInInitializerError
	at org.mockito.internal.exceptions.stacktrace.ConditionalStackTraceFilter.<init>(ConditionalStackTraceFilter.java:17)
	at org.mockito.exceptions.base.MockitoException.filterStackTrace(MockitoException.java:41)
	at org.mockito.exceptions.base.MockitoException.<init>(MockitoException.java:30)
	at org.mockito.exceptions.misusing.MockitoConfigurationException.<init>(MockitoConfigurationException.java:18)
	at org.mockito.internal.configuration.plugins.PluginLoader.loadImpl(PluginLoader.java:66)
	// 更多的堆栈信息...


希望这能帮助您解决问题。

I have seen a number of similar questions, but none of them seem to answer this. I keep getting `ExceptionInInitializerError` no matter what I try do:

```java
import static org.junit.Assert.fail;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;

import org.mockito.MockitoAnnotations;
import org.mockito.runners.MockitoJUnitRunner;
import org.springframework.web.client.RestTemplate;    

import org.springframework.web.client.RestTemplate;


@RunWith(MockitoJUnitRunner.class)
public class ClassTest {

    @Mock
    private RestTemplate mockedRestTemplate;


    @Before
    public void setup() {
	    MockitoAnnotations.initMocks(this);
    }

    @Test
    public void test() {	
	    fail(&quot;Not IMMM&quot;);
    }

}

I have also tried @RunWith(SpringRunner.class) but still the same error.

我遇到了相同的问题。通过将po.xml中的依赖项更改如下来解决了它。首先，它是mokito-all，将其更改为mokito-core。

<dependency>
  <groupId>org.mockito</groupId>
  <artifactId>mockito-core</artifactId>
  <version>4.0.0</version>
  <scope>test</scope>
</dependency>

I Was experiencing the same issue. Fixed it by changing the dependency in the po.xml as follows. At first, it was mokito-all. changed it to mokito-core.

&lt;dependency&gt;
  &lt;groupId&gt;org.mockito&lt;/groupId&gt;
  &lt;artifactId&gt;mockito-core&lt;/artifactId&gt;
  &lt;version&gt;4.0.0&lt;/version&gt;
  &lt;scope&gt;test&lt;/scope&gt;
&lt;/dependency&gt;
