# gradle

I've just upgraded to latest IDEA and Kotlin plugin v 1.4.20 and I m getting "Cannot access class java.io.File" or "Cannot access class java.net.URI" in the build scripts across the whole project. Has anyone experienced that?

Check in the IDE settings that there are no old or incorrect JDK entries.
Afterwards clear IDE cache & restart

[Kuba Petržílka]

can you be a bit more specific please what do you mean by "old JDK entries"? we are using JDK 1.8 in our project

File > Project Structure > Project > Project SDK > Edit

[Marc Knaup]

Make sure that list is cleaned up

mine

I dont see any problems there or?

[Marc Knaup]

Mhh looks good 😕
Then the only idea I’ve left is clearing IDE caches & restart

File > Invalidate Caches / Restart…

When I switch to JDK 14 in the Gradle settings, then the problems are gone, but our project doesn't compile with JDK14 coz we depend on some old Xml bind stuff 🙄

[Marc Knaup]

Maybe it’s an issue with Open JDK? 🤔

[Marc Knaup]

or that specific 1.8 release

[Marc Knaup]

or just a cache issue

[Kuba Petržílka]

hm, I did clean cache and restart plus reimport of the gradle project.. it took some time but I m back where I was

[Kuba Petržílka]

it is strange that it used to work normally with 1.4.10 and IDEA 2020.2

[Kuba Petržílka]

on the same JDK

[Kuba Petržílka]

but I will try to get latest 1.8 JDK and I ll see

[Marc Knaup]

Yeah that issue pops up often with IDE/Kotlin updates

[Marc Knaup]

I also had that with 1.4.0

[Marc Knaup]

causes differ though

[Kuba Petržílka]

Alright, thanks a lot mate, I upgraded the OpenJDK from 252 to 273 and it works now

[henrik]

Hmm, I have the same problem with jdk15. I'll try to invalidate the cache..
