Please perform full project rebuild (Build | Rebuild Project)

java: openjdk-11+28_osx-x64_bin.tar.gz

os: macOS 10.13.2

intellij: ideaIC-2018.2.4

Answer 1

Java 11 is still very new.

I suspect IntelliJ's caches got corrupted and clearing them should help.

I would also keep Intellij up to date if using such a new JDK.

Answer 2

同样的错误，升级到intellij 2018.1，错误消失了。

Answer 3

Open "Registry..." (double-press shift and type Registry ). If compiler.process.jdk is not at default, reset the registry to defaults.
