Description

The @react-native/gradle-plugin bundles settings.gradle.kts with:

plugins { id("org.gradle.toolchains.foojay-resolver-convention").version("0.5.0") }

React Native 0.83.x uses Gradle 9.0.0 (set in gradle/wrapper/gradle-wrapper.properties), but foojay-resolver-convention 0.5.0 depends on FoojayToolchainsPlugin, a class that was removed in Gradle 9.0.0.

This causes a build failure on any fresh project or after clearing Gradle caches.

Steps to reproduce

npx create-expo-app@latest --template default@sdk-55
cd <project>
rm -rf ~/.gradle/caches
npx expo run:android

Error

FAILURE: Build failed with an exception.

* Where:
Settings file 'android/settings.gradle' line: 21

* What went wrong:
Error resolving plugin [id: 'com.facebook.react.settings']
> org/gradle/toolchains/foojay/FoojayToolchainsPlugin

Full stacktrace:

Caused by: java.lang.NoClassDefFoundError: org/gradle/toolchains/foojay/FoojayToolchainsPlugin
    at org.gradle.toolchains.foojay.FoojayToolchainsConventionPlugin.apply(FoojayToolchainsConventionPlugin.kt:11)

Root cause

Component Version
react-native 0.83.4
@react-native/gradle-plugin 0.83.4
Gradle 9.0.0
foojay-resolver-convention 0.5.0

Gradle 9.0.0 removed the FoojayToolchainsPlugin class that foojay 0.5.0 depends on. Versions 0.8.0+ of foojay-resolver-convention are compatible with Gradle 9.0.0.

Verified fix

Updating settings.gradle.kts in @react-native/gradle-plugin from:

plugins { id("org.gradle.toolchains.foojay-resolver-convention").version("0.5.0") }

to:

plugins { id("org.gradle.toolchains.foojay-resolver-convention").version("0.9.0") }

resolves the issue. The build also requires --no-configure-on-demand to avoid a related metadata.bin generation failure.

Affected versions

  • react-native 0.83.0 through 0.84.1 (all ship foojay 0.5.0 with Gradle 9.0.0)
  • Expo SDK 55 (uses react-native 0.83.x)
  • Reproducible on macOS (ARM64) with Java 17 and Node 24

Environment

System: macOS 26.3.1 (arm64)
Node: v24.14.0
Java: OpenJDK 17.0.18 (Zulu)
Gradle: 9.0.0
react-native: 0.83.4
Expo SDK: 55.0.9

    Reproducer

    https://github.com/brunovmartin/react-native-foojay-reproducer

    This is a fresh project created with:

    npx create-expo-app@latest --template default@sdk-55

    No modifications. To reproduce:

    git clone https://github.com/brunovmartin/react-native-foojay-reproducer.git
cd react-native-foojay-reproducer
npm install
rm -rf ~/.gradle/caches  # ensure no stale cache masks the bug
npx expo run:android

    The build fails at settings.gradle line 21 with NoClassDefFoundError: org/gradle/toolchains/foojay/FoojayToolchainsPlugin.

    Root cause: @react-native/gradle-plugin@0.83.4 ships settings.gradle.kts with foojay-resolver-convention version 0.5.0, which references a class removed in Gradle 9.0.0. The same @react-native/gradle-plugin ships gradle-wrapper.properties pointing to Gradle 9.0.0, creating an internal incompatibility.

    Fix: Update foojay-resolver-convention from 0.5.0 to 0.9.0 in @react-native/gradle-plugin/settings.gradle.kts.

    This affects react-native 0.83.0 through 0.84.1.

    This is a build/upgrade related bug. The reproducer is a project using the official Expo SDK 55 template (npx create-expo-app@latest --template default@sdk-55) with zero modifications:

    https://github.com/brunovmartin/react-native-foojay-reproducer

    This is not reproducible via Snack or RNTesterPlayground since it's a Gradle build-time failure, not a runtime UI bug.

    The issue is purely in @react-native/gradle-plugin's settings.gradle.kts — it ships foojay-resolver-convention version 0.5.0 alongside a gradle-wrapper.properties pointing to Gradle 9.0.0. These two are incompatible: Gradle 9.0.0 removed the FoojayToolchainsPlugin class that foojay 0.5.0 depends on.

    To reproduce:

    git clone https://github.com/brunovmartin/react-native-foojay-reproducer.git
cd react-native-foojay-reproducer
npm install
rm -rf ~/.gradle/caches
npx expo run:android

    One-line fix in @react-native/gradle-plugin/settings.gradle.kts:

    - plugins { id("org.gradle.toolchains.foojay-resolver-convention").version("0.5.0") }
+ plugins { id("org.gradle.toolchains.foojay-resolver-convention").version("0.9.0") }

    see #56210, it's been resolved. @TheNerdGuyLulu can you also backport it from version 0.82.x to 0.84.x.

    Hey, bro , I'm currently stuck at this step. I found this issue, but I still managed to solve it following the method provided in the issue. I'm not quite sure if it was this plugin that caused the problem.

    npx expo run:android
npm warn Unknown user config "home". This will stop working in the next major version of npm. See `npm help npmrc` for supported config options.
