IntelliJ IDEA adding JDK 10: “The selected directory is not a valid home for JDK”

Question

I'm creating this question only because the duplicate questions I found were marked with Windows and Ubuntu respectively, whereas I am experiencing this issue on macOS

I have IntelliJ Ultimate 2017.2 installed, with JDK 8 added, and want to add JDK 10. After downloading and installing Oracle's JDK 10, and attempting to add /Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home as a new JDK to IntelliJ, I got the error message

The selected directory is not a valid home for JDK

despite the fact that the path and file permissions of this JDK 10 directory were seemingly all aligned with the JDK 8 ones.

It turned out that upgrading to the newest IntelliJ IDEA version was (for some reason) what was required. After installing IDEA 2018.1, I was able to add JDK 10 without issue.

Which is like the first thought after reading the question title :-) – GhostCat Jun 05 '18 at 12:22
But after upgrading to Intellij IDEA 2018, I'm encountering at least four different types of bugs that severely affect my productivity, none of which existed in the 2017 version. – RestInPeace Jun 05 '18 at 14:52

@Zarathustra were you able to get Java 10 to work with IDEA 2018.2? – Gabe Vacaliuc Oct 24 '18 at 22:34

@Gabe Vacaliuc downloading it from openjdk directly instead of via apt / yum – Zarathustra Oct 25 '18 at 12:02
