Where does IntelliJ store the JDKs that it downloads on my behalf?

Question

Recent versions of IntelliJ can download a JDK for the convenience of the user.

However, those downloaded JDKs are not appearing in the canonical place, at least not on my Mac:

/Library/Java/JavaVirtualMachines 

So where are the downloaded JDKs being stored?

I would like to inspect them, and possibly delete some.

I have found this documentation page, SDKs, but did not see the storage location mentioned there.

Answer 1

tl;dr

/Users/your_username_here/Library/Java/JavaVirtualMachines/

Details

You can inspect the JDKs known to IntelliJ by choosing File > Project Structure > Platform Settings > SDKs.

Notice how the location of the selected JDK is shown in the JDK home path field.

In this example, the JDK downloaded by IntelliJ was put in:

/Users/your_username_here/Library/Java/JavaVirtualMachines/

Note that this location contrasts with the location used by some of the independent JDK installers. In my experience, those tools use the root /Library path, rather than in the user’s ~/Library. That full path would be: /Library/Java/JavaVirtualMachines.
