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.

Solution

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 :-)

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.

does not work for me with IDEA 2018.2 for java 10 and 11 :/

@Zarathustra were you able to get Java 10 to work with IDEA 2018.2?

@Gabe Vacaliuc downloading it from openjdk directly instead of via apt / yum
