Summary:

This PR adds pull-through cache support for React Native Maven artifacts by trying https://rnmaven.swmtest.xyz/ before Maven Central for release artifacts.

  • Updates the Android Gradle resolution by adding cache repository before mavenCentral() scoped to React Native groups via includeGroupByRegex.
  • Updates iOS CocoaPods prebuilt artifact resolution to try the cache first, then fall back to https://repo1.maven.org/maven2.
  • Updates SwiftPM/iOS prebuild JS tooling with the same cache-first fallback behavior.
  • Preserves ENTERPRISE_REPOSITORY behavior as an explicit single custom repository override.
  • Avoids duplicate artifact existence probes in Ruby and JS by checking candidate URLs directly and caching JS HEAD results within the process.

Changelog:

[GENERAL][CHANGED] - Add React Native Maven pull-through cache fallback for prebuilt artifacts.

Test Plan:

Run:

react-native % RN_DEP_VERSION=0.81.0 \
HERMES_VERSION=250829098.0.13 \
node scripts/ios-prebuild -s -f Debug

The logs confirm that React Native artifacts are cached and pulled from the proxy:

[ReactNativeDependencies] Using download prebuild Debug tarball
[ReactNativeDependencies] Using release tarball from URL: https://rnmaven.swmtest.xyz/com/facebook/react/react-native-artifacts/0.81.0/react-native-artifacts-0.81.0-reactnative-dependencies-debug.tar.gz
[ReactNativeDependencies] Downloading ReactNativeDependencies tarball from https://rnmaven.swmtest.xyz/com/facebook/react/react-native-artifacts/0.81.0/react-native-artifacts-0.81.0-reactnative-dependencies-debug.tar.gz

Added gradle plugin tests which can be run with:

./gradlew :react-native-gradle-plugin:test --tests com.facebook.react.utils.DependencyUtilsTest

I think we probably want to add a kill-switch that disables this entirely, like a react.internal.enableReactNativeRepoMirror=false gradle property (naming up for debate).

We would need the same for iOS

I think that RepoMirror is a bit vague here. How about changing it to reactNativeMavenCacheEnabled?

Yeah, anything specific that we want to have there? We added artifacts explorer like on repo1.maven.org.
