JDKs installed with SDKMAN are not selectable in the IntelliJ IDE

Question

What steps will reproduce the issue?

• Install SDKMAN (https://sdkman.io) commandline tool
• Install one or more JDK using sdkman eg.: sdk install java 8.0.232-zulu
• Open a project in IntelliJ IDEA
• Navigate to the "Set home directory for JDK" window: File » Project Structure » SDKs » + (button) » JDK
• Select "Show hidden files and directories"
• Navigate to ~/.sdkman/candidates/java
• The installed JDK versions should be shown here - but the folders cannot be opened

What is the expected result?

The installed JDK should be selectable

What happens instead?

The folders containing the JDKs are not displayed in the browser (image #3) I need to switch back to JDK 8 and currently I can only use the IDEs built in JDK11 (cannot select either the 11 or 8 JDK versions installed through SDKMAN)

Environment

OS: Linux Mint IntelliJ IDEA 2019.3 (Community Edition) Build #IC-193.5233.102, built on November 28, 2019

Answer 1

For me both of of the below helped to resolved.

1. Invalidate cache (File > Invalidate Caches / Restart)
2. Update the IntelliJ version to 2021.x (This would solve much of ur problem!)

Answer 2

If Planning to use Java 14 (Preview - Record, patterns, text blocks), make to have switched to IntelliJ 2020.1 update. then, you can press (cmd + ;) for mac to open project/module settings and select Java 14 JDK and language level Java 14 (Preview - Record, patterns, text blocks)

Answer 3

Use File > Invalidate Caches / Restart option which should invalidate local caches. Hopefully it's a glitch in the dialog cache.
