我正在为
Eclipse开普勒开发一个插件.将@RunWith(JMockit.class)添加到我的测试类会导致以下错误:

我做错了什么,还是JMockIt错误?我使用版本JMockIt 1.18,JUnit 4.12
解决方法
我会期望@RunWith(JMockit.class)应该照顾这个问题.
在任何情况下,从JMockit教程here,有一些注释,你应该检查,以防这些解决你的问题.特别是这两个似乎是最相关的:
- (Note for Eclipse users: when specifying the order of jars in the >classpath,make sure to use the “Order and Export” tab of the “Java Build >Path” window. Also,make sure the Eclipse project uses the JRE from a JDK >installation instead of a “plain” JRE,since the latter lacks the >”attach” native library.)
- In other situations (like running on JDK implementations other than >the Oracle JDKs),you may need to pass “-javaagent:path>/jmockit.jar” as a JVM initialization parameter. This can be done in >the “Run/Debug Configuration” for both Eclipse and IntelliJ IDEA,or with >build tools such as Ant and Maven.
