Back-End (JVM) internal error. Why do i get this IDE error but others with the same code do not? - kotlin

Question

I'm part of a group that is developing a program in Kotlin. I have recently pulled fresh code off the development branch. The problem is i get this strange error. I am the only person that gets it; my groupmates have the same code and it runs fine for them.
I've tried googling for the error. I didn't find any help as it is quite a specific one. Plus like i said my groupmates do not get this error. It is therefore probably not related to the code.
The error i get is this:
Error:Kotlin: [Internal Error] java.lang.IllegalStateException: Backend Internal error: Exception during code generation

I'm sure this has to do with my IDE or some local setting. Again, my groupmates don't get this error. The file that is mentioned in the error, EndRoundState.kt, however looks like this. If this helps clarify my problem.

I just want the code to compile on my machine, like it does for my collegues. It does compile through Maven, just not through IntelliJ.
Thank you very much!

Answer 1

I fixed by just upgrading kotlin plugin. My plugin version currently is 1.3.41-release-IJ2018.2-1

Answer 2

I resolved this issue by uninstalling IntelliJ including all settings/plugins and reinstalling.
Uninstalling the IDE without removing settings/plugins did not work.

Answer 3

I've encountered this in one of our test-cases where we had a function with a long name.
Granted this development machine was a Windows 10 machine, and Windows has a history of having problems with long filenames, https://community.spiceworks.com/topic/2006950-file-path-too-long-shortening-names-is-only-the-solution.
Try to see if the filename or the function names is too long and shorten it.
It certainly helped me to reduce the 93 character test function name to 70 characters.
Also check to see if you are using weird characters and emojis, some times they can mess up the file generation.
Have fun and be safe out there.

Answer 4

In my case, it was caused by using my custom suspend operator fun plusAssign and calling it by +=. When I replace the += by explicit plusAssign, it compiles fine. I can also use the same += elsewhere just fine. No idea what's going on.
