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/Homeas a new JDK to IntelliJ, I got the error message
我安装了 IntelliJ Ultimate 2017.2，添加了 JDK 8，并想添加 JDK 10。下载并安装 Oracle 的 JDK 10，并尝试将/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home新 JDK添加为 IntelliJ 后，我收到错误消息
The selected directory is not a valid home for JDK
所选目录不是 JDK 的有效主目录
despite the fact that the path and file permissions of this JDK 10 directory were seemingly all aligned with the JDK 8 ones.
尽管这个 JDK 10 目录的路径和文件权限似乎都与 JDK 8 一致。

It turned out that upgrading to the newest IntelliJ IDEAversion was (for some reason) what was required. After installing IDEA 2018.1, I was able to add JDK 10 without issue.
事实证明，升级到最新的 IntelliJ IDEA版本是（出于某种原因）所需要的。安装 IDEA 2018.1 后，我可以毫无问题地添加 JDK 10。
