2.1.0-RC2 release should help you.

[Abhimanyu]

So, is it not fixed yet? 😕

[mglukhikh]

It is. The status is "fixed in 2.1.0-RC"

[Abhimanyu]

But, its not working for me.
Anything else I should do?

[mglukhikh]

You can try
• Set language version also 2.1
• Perform a rebuild

[Abhimanyu]

I have not done any manual changes for K2.
So, I am not sure how the project is not working now.

[Abhimanyu]

Language version should be set here or anywhere else?

Rebuilding shows the same error.

[Abhimanyu]

This is the repo, if that helps.

[mglukhikh]

Yes, it helps. For me it looks like a different problem, as rebuild does not help you. We will try to fix it in next RC or in 2.1.0

[Abhimanyu]

thank you color

[Abhimanyu]

Is there any workaround for this?

I have no need for K2 now.

[mglukhikh]

Try 1.9.25. Or 2.0.10.

[mglukhikh]

BTW, you have a Gradle Project, have you changed a compiler version there?

[Abhimanyu]

It showing the same error.

[mglukhikh]

It means you should make a change in your Gradle conf. It overrides Idea conf.

[mglukhikh]

With K1, you cannot get this error, it's K2 specific

[Abhimanyu]

Yes, works now. kodee happy

This line had to be updated.

pluginManagement {
    plugins {
        id 'org.jetbrains.kotlin.jvm' version '1.9.20'
    }
}

[mglukhikh]

Please try also 2.1.0-RC2 at the same place, does it work or not?

[Abhimanyu]

👌 , It works with 2.1.0-RC2 as well now.

[Abhimanyu]

Thank You thank you color

Yes, it helps. For me it looks like a different problem, as rebuild does not help you. We will try to fix it in next RC or in 2.1.0

Hi! @mglukhikh Could you please share the ticket to fix this issue?

[mglukhikh]

In fact the problem arose because Gradle script wasn't updated, so the used compiler version wasn't changed. No new issue here.
