IntelliJ Idea has neat feature – Terminal Window.
Unfortunately on Windows it’s set just to old school cmd. Good news is that it’s possible to change it to something better. E.g. PowerShell.
Go to project settings, type “terminal”. Change value in Shell path to powershell.exe.
Then you can invoke Terminal:
Note: If you’re using 32bit version of Idea then it will open 32bit version of PowerShell. This is important when you want to change Set-ExecutionPolicy. 32bit and 64bit PowerShell have two different settings.
