Intellij IDEA code coverage doesn't work

问题

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

Can anybody help to fix it?

Take a look here: https://youtrack.jetbrains.com/issue/IDEABKL-5941

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

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