The JDK 18.0.1 isn't compatible with Gradle 4.4.1-CodePudding

I used Mac Machine and IntelliJ Idea. I found this Compatibility Matrix of Gradel and Java. https://docs.gradle.org/current/userguide/compatibility.html

I try to import this project https://github.com/udacity/ud282 from Github and when I try to run build.Gradle it shows me error Message:

JDK 18.0.1 isn't compatible with Gradle 4.4.1. Please fix JAVA_HOME environment variable.

when I ask the shell to show me JAVA_HOME using echo $JAVA_HOME command it shows the path

/Users/lama/Library/Java/JavaVirtualMachines/openjdk-18.0.1.1/Contents/Home

And another error Message:

Unsupported Java. 
Your build is currently configured to use Java 16.0.2. It's recommended to use Gradle 7.0 or newer.

Possible solution:
 - Use Java 1.8 as Gradle JVM: Open Gradle settings 
 - Open Gradle wrapper settings, change `distributionUrl` property to use compatible Gradle version and reload the project

When I ask the shell about the Gradle version gradle -v it shows:

------------------------------------------------------------
Gradle 7.4.2

CodePudding user response：

The compatibility matrix you mentioned (https://docs.gradle.org/current/userguide/compatibility.html) specifically says no version of Gradle (currently at version 7.4.2) is compatible with Java 18 yet.

Your best bet is to try installing/switching to an older version of Java (like 8 perhaps) and running the ./gradlew wrapper as @Joachim Sauer suggested. That should automatically download and install Gradle 4.4.1.
