EAS Android build failed

CI (GitHub Actions, EAS, fastlane) · last reviewed 2026-11-10

The error looks like this

Gradle build failed with unknown error. See logs for the "Run gradlew" phase for more information.

Why it happens

EAS shows a summary only; the cause is in the "Run gradlew" step.

How to fix it

  1. Open the build page > "Run gradlew" phase, copy the FIRST "What went wrong" block.
  2. Run: releasemedic log on that text.

Not sure this is your error? Let ReleaseMedic read the whole log

Build logs are long and the last line is rarely the real cause. ReleaseMedic finds the first real error, explains it and gives the steps — free, and the log never leaves your computer.

$ npx releasemedic log build.log

Or pipe a build straight in: cd android && ./gradlew bundleRelease 2>&1 | npx releasemedic log -

Catch it before you build

Most release errors come from project settings you can check in seconds — signing, SDK levels, privacy manifests, permissions, push and login setup.

$ npx releasemedic
