After upgrading my Kepler Native SDK from version 0.14.6 to 0.20.3719, I attempted to build the sample native app on my Mac. However, the build fails with several `:0:error:package not found` logs before the process is stopped by Ninja. The final reported error is: [native-build] kepler ktbuild exited with code 254 2025-11-14 14:11:33 error [BuildHandler]: There was an error that caused all build configurations for build tasks to exit. **Observations** : Packages not found: The build process reports several packages are missing. Some of the packages that it was unable to find: `com.amazon.kepler.tv.kepler_channel_server2` `com.amazon.kepler.tv.epg_provider` `com.amazon.kepler.tv.epg_provider_models` `com.amazon.kepler.tv.personalization` `com.amazon.kepler.net.common` `com.amazon.kepler.net.net_manager` `com.amazon.kepler.w3cmedia` Missing `buildinfo.json` According to the docs, the downloaded native sample app should include a `buildinfo.json` file in it’s root directory. However, this file is missing in my project directory. `kepler platform doctor` reports no issues Environment details: SDK Version: 0.20.3719 Previous SDK version: 0.14.6 Mac : M1 Pro macOS : Sequoia 15.6.1 build command used: `kepler build` and build through kepler extension Any guidance on resolving this issue would be appreciated. Thank you ---

Hi Ivy, I sent a DM with this information a couple of weeks ago, with the title “RE: Kepler native app build fails after upgrading sdk from 0.14.6 to 0.20.3719” . I’d provide it here, but the logs have some PID that I would like to keep out of the public forum. ---
