java.lang.NoClassDefFoundError:无法初始化类org.mockito.internal.util.MockUtil

我想使用testng+powermock+spring来运行测试代码，我的jar版本是：

powermock = 1.6.2
powermock-module-testng = 1.6.2 
mockito = 1.10.19
testng = 6.8.7
spring = 4.1.1.RELEASE
JDK = 1.8.0

我的测试代码如下，并没有扩展AutoBaseTest，可以正常运行，AutoBaseTest包含 @ContextConfiguration（位置={”/test/resources/applicationContext test.xml“}）

错误堆栈：

当上下文类加载器不同于用于加载PowerMock和Mockito的加载器时，它与加载插件是一个很好的结合

它可以在Mockito2中修复，但正如它在评论中提到的那样

不确定我们是否有构建基础设施来支持1.x上的修复

---

对于Mockito 1，修复程序无法交付，所以我在PowerMock中进行了修复，修复程序将包含在下一个PowerMock版本（）中

java.lang.NoClassDefFoundError:无法初始化类org.mockito.internal.util.MockUtil==>lokks，就像您缺少一些依赖项一样。mockito-all-1.10.19.jar mockito-core-1.10.19.jar powermock-api-mockito-1.6.2.jar powermock-core-1.6.2.jar powermock-api-supportpowermock-module-junit4-1.6.2.jar powermock-module-junit4-common-1.6.2.jar powermock-module-testng-1.6.2.jar确保您遵循了一起使用testng和powermock的建议，特别是关于

PowerMockObjectFactory

的建议。一旦使用了正确的工厂，您可能会发现您的问题更容易诊断。@PankajKatiyar和@stephen hartley我在运行PowerMock测试时也遇到了给定的问题，但我仍然无法确定发生了什么。我想它以前起过作用，但我不确定。正如您可能看到的第一个例外，我们在

（Plugins.java:17）

上有NPE，我认为它与类加载器有某种联系。对于jUnit模块，我也会遇到同样的问题。

AutoBaseTest

或者它的祖先之一能够扩展

PowerMockTestCase

？我只能在不扩展

PowerMockTestCase

时重现此问题。
