PowerMockito：java.lang.NoClassDefFoundError

private MyFinalClient client;

@Before
public void setup() {

    // set up mock
    client = PowerMockito.mock(MyFinalClient.class);
    service = new PatientLocationService();
    service.setClient(client);
}

当我运行测试时,我将收到以下错误消息：

不完全确定为什么我得到这个……如果我在Spring Tool Suite中执行此操作,这将不会产生任何错误,但会在命令提示符和IntelliJ中断开(在正常的eclipse中)

请帮忙！

谢谢！

编辑：
这是powermock信息：

<dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-api-mockito</artifactId>
        <version>1.6.2</version>
        <scope>test</scope>
    </dependency>

我正在使用spring boot starter test,从类路径我可以看到我正在使用：

> mockito-all-1.9.5
> mockito-core-1.10.19

我通过import->现有的Maven项目(通过包含pom.xml)导入了项目,在Idea中我也做了类似的事情……
