问在PowerMockito中的java.lang.NoClassDefFoundError？

使用的依赖：<dependency> <groupId>org.mockito</groupId> <artifactId>mockito-all</artifactId> <version>2.0.2-beta</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.powermock</groupId> <artifactId>powermock-module-junit4</artifactId> <version>2.0.0-RC.4</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.powermock</groupId> <artifactId>powermock-api-mockito</artifactId> <version>1.7.4</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.powermock</groupId> <artifactId>powermock-core</artifactId> <version>2.0.0-RC.4</version> <scope>compile</scope> </dependency>

在模拟mock出来的类时，报错java.lang.NoClassDefFoundError错：

下面时错误的完整跟踪：
