... Fixed in commit 7e3503b. The KAPT error was caused by Kotlin 2.1.0 using the K2 compiler by default, which KAPT doesn't fully support without explicit configuration.

Room 2.6.1 doesn't support Kotlin 2.1.0 metadata. Updated to Room 2.7.0 which includes support for Kotlin 2.0+ metadata versions. This fixes the KAPT error: "Provided Metadata instance has version 2.1.0, while maximum supported version is 2.0.0".

Fixed in commit d62b23d. The build was failing because Room 2.6.1 doesn't support Kotlin 2.1.0 metadata. Updated Room to 2.7.0 which includes support for the new Kotlin metadata format. Build & Tests: ✅ SUCCESS

The build passed this time. It took me ten premium requests that would have taken one otherwise had I checked the firewall warning on the other PR and added the websites suggested in this blog. Hope this helps it solve other tasks that we'll assign it :) |
