当我尝试在覆盖范围内运行JUnit测试时，出现以下错误

When I'm trying to run my JUnit tests with coverage I receive the following error

有人可以帮助修复它吗?

Can anybody help to fix it?

推荐答案

在这里看看: https://youtrack.jetbrains.com/issue/IDEABKL-5941

您可以将-Djava.io.tmpdir参数添加到idea的启动脚本中，或替换TMP系统属性.

You can add -Djava.io.tmpdir param to idea's launching script or replace TMP system property.

也许您还必须在安装目录中的idea.properties中更改idea.config.path和idea.system.path.

Also probably you will have to change idea.config.path and idea.system.path in idea.properties in installation directory.
