无法初始化 Mockito

Question

我正在尝试设置 Mockito 2.22 并已下载 mockito-core-2.22.2.jar and byte-buddy-1.9.0.jar，并且在 Netbeans 8.2 项目中，我已将这两个 jar 文件 JUnit 4.12 和 Hamcrest 1.3 添加到测试库。

当我尝试运行 MCVE 时：

package com.Whosebug.test;

import org.junit.Test;
import static org.mockito.Mockito.mock;

public class SimpleMockTest {
    public static class A{
        public String value(){ return "A"; }
    }
    @Test
    public void testASimpleMock()
    {
        A mocked = mock( A.class );
    }
}

当我尝试运行测试时，出现错误：

我还缺少其他依赖项吗？或者需要做一些其他 configuration/annotiation/setup 来修复错误并允许对象被模拟？

Answer 1

@JBNizet 关于使用 Maven 的建议让我找到了 Mockito's maven pom，其中列出了依赖项：

字节好友 1.9.0
byte-buddy-agent 1.9.0
对象 2.6

下载 objenesis 并将其添加到项目中解决了问题。
