After upgrading the IDE plugin to 1.4.21, the plugin now throws Gradle-related exceptions all the time and there is no code completion in .gradle-kts files anymore. After downgrading to 1.4.10 it works again. I cannot find a 1.4.20 release for 2020.3. Does anybody know a page where you can see all releases?

[kqr]

how did you get version 1.4.21, mine shows 1.4.10 as latest

[kqr]

hm insteresting when I check for updates it says there is no updates, but in settings there is a newer version

[ikej]

I'm looking here: https://plugins.jetbrains.com/plugin/6954-kotlin/versions

I had 1.4.20 before for 2020.3 and now I cannot get it back.

This is the first exception that is thrown with 1.4.21:

[ikej]

After that there are other exceptions.

[Alexey Belkov [JB]]

1.4.20 for 2020.3 was released in EAP channel: https://plugins.jetbrains.com/plugin/6954-kotlin/versions/eap. However, it's unlikely that something broke in 1.4.21 and works OK in 1.4.20. Can you share exception stack trace?

[ikej]

Thank you, I'll try if that makes any difference.

[ikej]

Just tried it, and the 1.4.20 plugin does not throw this exception and completion in .gradle.kts files works correctly.

[Alexey Belkov [JB]]

This problem looks like https://youtrack.jetbrains.com/issue/KT-42828 (please see discussion there) or https://youtrack.jetbrains.com/issue/KT-42769. But it doesn't look like 1.4.21 regression.

[ikej]

Yes, I get "updateRootsCache" exception after that as well. I will now try once more again if upgrading to 1.4.21 causes these exceptions to reappear.

[Alexey Belkov [JB]]

I'm not sure but it may help to remove .gradle and .idea directories and reimport the project into IDEA

[ikej]

I deleted .gradle, .idea and buildSrc/.gradle, but that makes no difference. 1.4.21 throws these exceptions for me and 1.4.20 does not. Unfortunately I have now reached a state where 1.4.20 shows all .gradle.kts files as red and nothing helps, even invalidating caches. Everything works with 1.4.10, though. I understand that 1.4.20 included extensive upgrades to the way that .gradle.kts files are handled, so probably it is related to that.

[Alexey Belkov [JB]]

Does it help to delete caches manually as described in https://youtrack.jetbrains.com/issue/IDEA-245027?

[ikej]

Yes, indeed, now it works with 1.4.21! Thank you very much for your help. As a suggestion, maybe the "Invalidate caches" action should do just that.

Hi. Any other solution for this ? I am having kotlin 1.4.21 and KMM project. I am using Android Studio. It shows standalone scripts in my project although I have manually deleted them from the project and but still it shows there. Have tried mention solutions from https://youtrack.jetbrains.com/issue/KT-42828 but doesn't work. Invalidate cache and restart works only for the first time and then again same issue. I have tried deleting gradle cache manually from but doesn't help.
