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

Question

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:

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?

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
