Gradle could not download dependencies

Android / Gradle · last reviewed 2026-11-10

The error looks like this

Could not resolve all files for configuration ':app:debugRuntimeClasspath'.

Why it happens

Network/proxy problem, a removed repository (jcenter), or a version that does not exist.

How to fix it

  1. Read which artifact failed. If it mentions jcenter: replace with mavenCentral().
  2. Retry with --refresh-dependencies.
  3. Check the library version exists.

$ 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.
