Intellij project with idea.sh

[Sergei Ustimenko]

Hi Maurizio,

Thanks for the quick reply!
Thanks, now I see that excluding the classes and no SDK in the beginning are by design.

It seems that I've solved the problem: I do use the latest built version of the SDK i.e. 18
(as well as openjdk-16), the problem in my case with modules was that I had to set the
language level to (in my case) "16 Sealed Types" or to "X - experimental features".
It was (I think) malformed, so when I switched it to "16" and then to "X" then it worked.
With a small note that in .idea/misc.xml it is still:
<component name="ProjectRootManager" ... languageLevel="JDK_16_PREVIEW" ... project-jdk-name="18-ea" project-jdk-type="JavaSDK">
...
</component>
Though, problems with modules are not visible now - hope it helps others.

I've seen there is a documentation placeholder for IDE support for Java code in doc/ide.md. Is it
something that we could update to reflect steps for Intellij for Java, what do you think?

Cheers,
Sergei
