How supported is it to downgrade the IDEA version used to open a given project? If I opened a project with 2022.3, is it ok to open it with 2022.2 without re-importing the project?
In other terms, is the .idea binary format forward compatible? 😅

When I have problems related to moving from AS to IntelliJ I just delete the .idea project

and I reopen the project to regenerate it

[mbonnin]

Yea, I do the same too but it's a bit cumbersome

At least would be nice to have an explicit error that points to the correct solution so that I don't remove ~/.m2 and ~/.gradle when only .idea was needed

[mbonnin]

Right now I'm hit with

Directory '/Users/mbonnin/git' does not contain a Gradle build.

when opening /Users/mbonnin/git/apollo-kotlin with an "older" IDEA

I would say probably never need to delete files in ~/.m2 or ~/.gradle. I can not think of a time when that has been required, and I've used idea for a long time. Rolling forward I'd expect no issues, but rolling back, probably not.

I've needed to delete ~/Library/Application\ Support/JetBrains/IdeaIC2022.3 recently

[mbonnin]

In all cases, a better error than

Directory '/Users/mbonnin/git' does not contain a Gradle build.

would be nice
