我正在为Eclipse Kepler开发一个插件。将@RunWith（JMockit.class）添加到我的测试类中会导致以下错误：

是我做错了什么，还是JMockIt有错误？我使用的是JMockIt 1.18版本，JUnit 4.12

我希望@RunWith(JMockit.class)应该已经处理了这个问题。
在任何情况下，从JMockit教程这里，有一些注意事项，你应该检查，如果这些解决你的问题。特别是，这两个似乎是最相关的：

（Eclipse用户注意：当在〉类路径中指定jar的顺序时，确保使用“Java Build〉Path”窗口的“Order and Export”选项卡。另外，确保Eclipse项目使用来自JDK〉安装的JRE，而不是“plain”JRE，因为后者缺少〉“attach”本地库。
在其他情况下（比如在Oracle JDK以外的JDK实现上运行），您可能需要传递“-javaagent：path〉/jmockit.jar”作为JVM初始化参数。这可以在Eclipse和IntelliJ IDEA的“Run/Debug Configuration”中完成，或者使用Ant和Maven等构建工具完成。

在包资源管理器中右键单击项目
点击属性。2转到Java构建路径。3库标签。4点击“添加库”按钮选择JUnit，点击下一步。5你应该能够从那里处理它。
之后，如果您将保险用作：您将能够看到覆盖范围。

请通过VM参数传递以下参数。
