I have a scala-project, which I build with Maven via Intellij. Scala version is 2.12.18, Java version is 11. When i build one module, I get error: NoSuchElementException: head of empty list. I read about this error in other scala versions. In some cases it was a compiler bug, in some other it was a programmer fault. My project is big, I use in many places: Nil, Map.empty, etc. Can someone please guide me: if it my fault how can i find the place in code where i made this mistake (list.empty). Or how i can understand, that it's compiler bug. With Maven and scala-compiler-plugin I get only this stack trace without any useful information:

maven-scala-plugin is quite old, it's been renamed to scala-maven-plugin since then and it's current version (as of 2023) is 4.x: https://davidb.github.io/scala-maven-plugin/index.html.
I would upgrade the plugin version as from the stacktrace it looks like an error happening inside the plugin itself, it's not a compilation error: it's a runtime error in the compilation plugin.
It's probable that the error is caused by a compilation error but as you said you won't be able to find it without the compiler plugin helping you with the relevant line and file.
