I get the same error on Ubuntu 24.04 if i write
val terminal = Terminal(interactive = true)
val rawMode = terminal.enterRawMode()
When I copy the whole command that IntelliJ runs in a terminal, then I don't get an error message.
Thanks, I'll see if I can repro this locally. In the mean time, if you're able to use Java 22+ to test the FFM module to see if this is a JNA issue or not, that would be very helpful.
Sorry, I dont know what I should change in my Code. I loaded it in my Gradle-File. Now I get this error:
Exception in thread "main" java.lang.RuntimeException: failed to read terminal settings

Hi there! I faced with the same issue when I try to run the project with an interactive list multi-select directly in the IDEA. I use MacBook Pro M1 (MacOS 15.2 (24C101)) Meantime the run of the built .jar directly in the terminal works fine. Also if I comment the part of code responsible for the call of interactive list - everything also looks nice.
