java - PowerMockRunner 在运行简单测试时导致 ExceptionInInitializerError

我无法使用 Powermock 测试运行器运行非常简单的测试类。它会导致 ExceptionInInitializerError。它看起来是类路径上的依赖项的问题,但是,我尝试了依赖项版本的几个变体,但它们都会导致相同的错误。使用 Powermock 测试运行器时,如何才能让这个简单的测试通过?

测试代码:

package net.solasistim.hello;

import org.junit.Test;
import org.junit.Assert;
import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
public class HelloTest {
@Test
public void testMain() {
Assert.assertTrue(true);
}
}

项目 POM:

<project>
<modelVersion>4.0.0</modelVersion>
<groupId>net.solasistim.hello</groupId>
<artifactId>hello</artifactId>
<version>1</version>
<packaging>jar</packaging>

</project>

运行 mvn clean compile test 导致以下输出:

最佳答案

PowerMock 和最新的 cglib 似乎不太合得来。我不能告诉你确切的原因,但如果你从 3.0 降级到 2.2.2,它应该可以工作:

<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>2.2.2</version>
<scope>test</scope>
</dependency>
