Android Gradle plugin requires Java 11 to run You are currently using Java 1 8

Question

When I try to run flutter app on vs code. I get this error:

FAILURE: Build failed with an exception.

* Where:
Build file '/home/aman/Desktop/arjun_malhotra/flutter_Projects/isolates_demonstration/android/app/build.gradle' line: 24

* 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.
     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.

But I dont see my JVM pointing to 1.8 version. How do I resolve this?  Also I dont see any gradle option from where I can change version.

Hope this helps!

Based on the error message, the Android Gradle plugin requires Java 11 to run, but you are currently using Java 1.8. You can try one of the following options:

1. Change the IDE settings You can try changing the settings in your IDE (e.g. Android Studio or VS Code) to use Java 11 instead of Java 1.8.

2. Change the JAVA_HOME environment variable Set the JAVA_HOME environment variable to point to the Java 11 installation directory. To do this, follow these steps:

• Determine the path to the Java 11 installation directory.
• Set the JAVA_HOME environment variable to the path of the Java 11 installation directory.

For example, on Linux, you can set the JAVA_HOME environment variable by running the following command in a terminal:

export JAVA_HOME=/path/to/java-11

On Windows, you can set the JAVA_HOME environment variable by following these steps:

• Open the Control Panel.
• Click System and Security.
• Click System.
• Click Advanced system settings.
• Click Environment Variables.
• Under System Variables, click New.
• In the Variable Name field, enter JAVA_HOME.
• In the Variable Value field, enter the path to the Java 11 installation directory.

1. Change org.gradle.java.home in gradle.properties Set the org.gradle.java.home property in the gradle.properties file to point to the Java 11 installation directory. To do this, follow these steps:

• Determine the path to the Java 11 installation directory.
• Open the gradle.properties file in a text editor.
• Add the following line to the file:

org.gradle.java.home=/path/to/java-11

Replace /path/to/java-11 with the actual path to the Java 11 installation directory.

After making one of these changes, try running the flutter app again and see if the issue is resolved.
