React Native error: "Could not determine java version from '9.0.1'."

gradle, react-native

Solution

In your `PROJECT_PATH/android/gradle/wrapper/gradle-wrapper.properties` file, update your `distributionUrl` to the following:

distributionUrl=https\://services.gradle.org/distributions/gradle-5.0-all.zip

See related gradle distributions documentation

Problem

I'm working on MacOS and just starting with `react-native`. One of the first steps to get started is to run: `react-native run-android` or `react-native run-ios`. But I'm getting this error: ``` react-native run-android ``` Result: ``` Scanning folders for symlinks in /Users/ric/myprojs/albums/node_modules (6ms) Starting JS server... Building and installing the app on the device (cd android && ./gradlew installDebug)... FAILURE: Build failed with an exception. * What went wrong: Could not determine java version from '9.0.1'. * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Could not install the app on the device, read the error above for details. Make sure you have an Android emulator running or a device connected and have set up your Android development environment: https://facebook.github.io/react-native/docs/android-setup.html ``` This is what I get when I run `java --version`: ``` java --version ``` Result: ``` java 9.0.1 Java(TM) SE Runtime Environment (build 9.0.1+11) Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode) mbp:albums ric$ java --version java 9.0.1 Java(TM) SE Runtime Environment (build 9.0.1+11) Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode) ``` Edit My javac version: ``` javac --version ``` Result: ``` javac 9.0.1 ``` Any idea on how to fix this?
