关于异常：JMockit具有EclEmma代码覆盖问题

JMockit with EclEmma code coverage issue

在任何人否决我重复问题之前...。我已经阅读了与该主题相关的所有其他StackOverflow答案，但没有任何答案。

所以我正在使用JMockit 1.19，下面是我对Jmockit和Junit的pom.xml依赖关系

</dependency>

我正在使用通过Eclipse Marketplace安装的EclEmma 2.3.2插件。

但是，当我尝试查看代码覆盖率时，会同时遇到几个不同的问题。

我得到以下异常日志：

我还看到两个弹出式窗口……

popup 1) -"No coverage data has been collected during this coverage session. Please do not terminate the Java process manually from Eclipse."

pupup 2) -"Error while dumping coverage data (code 5013). com.mountainminds.eclemma.internal.core.launching.AgentServer"

为了使JMockit成功运行，我提供了JVM参数

1	-javaagent:C:/Users/vn90614/.m2/repository/org/jmockit/jmockit/1.19/jmockit-1.19.jar

我认为这个论点与问题有关
