IntelliJ Idea problem (1 reply)

I download plugins in intellij idea (and reimport) using this tutorial {[wordrider.net]}.
If i open TestApp (i test in uloz.to and ulozisko),in main it shows error.
{
Application.launch(TestApp.class, args);

launch (Java.lang.Class , String[]) in Application cannot be applied
to (Java.lang.Class, String[])
}
