当我尝试使用 IBM JDK 运行简单的 jMockit/JUnit 测试时遇到以下异常。

为此，我在运行配置中传递了 VM 参数，但出现以下错误：

JVMJ9VM007E 无法识别命令行选项：-javaagent=C:\Users\junit\jmockit.jar

有人遇到过这个问题吗？我们将不胜感激。

【解决方案1】：

您可以尝试添加以下参数 -Dcom.ibm.tools.attach.enable=yes 并且 jdk tools.jar 文件应该在您的类路径中

另外，请查看这篇与您的惊人相似的帖子。根据接受的答案，其中一个发行版中存在一个错误，需要在类路径中使用 TestNG 作为解决方法。 AttachNotSupportedException while running jMockit tests on IBM JRE
