Gradle 检测到 Java 1.8 而不是 Java 11

Question

When creating a new project with

npx react-native init newProject

and start the app by

npx react-native run-android

I will receive this error:

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\path\newProject\android\app\build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':app'.
> Failed to apply plugin 'com.android.internal.application'.
   > Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
     Your current JDK is located in  C:\Program Files\OpenJDK\openjdk-8u292-b10\jre
     You can try some of the following options:
       - changing the IDE settings.
       - changing the JAVA_HOME environment variable.
       - changing `org.gradle.java.home` in `gradle.properties`.

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

I have tried it with other gradle versions and other react native versions, but the error still persists. Existing projects are working...

You need to install Java 11 on your system and update the JAVA_HOME and PATH variables on your system. If you are using Windows, you can add or update it under environment variables. For Linux-based systems, you can just add these commands to to your profile file:

export JAVA_HOME="java11path"

export PATH=$JAVA_HOME/bin:$PATH
