Kepler native app build fails after upgrading sdk from 0.14.6 to 0.20.3719

Vega Open Beta Q&A
1

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.

@Justin2 I believe I have not received the logs, may I know who you shared it with please?

Warm regards,
Ivy
