compatibility with jmockit

when I use this plugin in our project. I got the error trace below:

it seems that this plugin is not compatible with jmockit? we can successfully run test in intellij idea without plugin, but throw error when using sbt shell. So I suppose we need your plugin. please help us~ Thanks

@zzmzz I am unfortunately not familiar with jmockit. Could you please provide a bare minimum sbt project which shows the reported issue ? Thanks !
