I am trying to build docker image using ktor plugin and java version 20 but I am getting jib error.

Unsupported class file major versio  64

How can resolve this without changing java version

What’s the error message? I use jib directly: <https://github.com/hfhbd/ComposeTodo/blob/main/backend/build.gradle.kts|https://github.com/hfhbd/ComposeTodo/blob/main/backend/build.gradle.kts>

Maybe i am giving incorrect name for jib.from.image

This looks the same way I am trying

But still the same issue
