In IntelliJ IDEA, could not run Gradle for the master branch of the selenium-webdriver-java project

[kazurayam]

I cloned out the master branch of https://github.com/kazurayam/selenium-webdriver-java. I just opend it in the IntelliJ IDEA. IntelliJ IDEA showed error messages in the Build tab.

The messages in the Build tab was:

I checked IntelliJ IDEA > Preferences > Build, Execution, Deployment > Build Tools > Gradle

I found the JVM for Gradle is set to be JDK8. It's too old!

[kazurayam]

I changed the IntelliJ IDEA's config to set the Gradle JVM to be JDK17:

I stoped IDEA and restarted it. I re-opend the selenium-webdriver-java project.

In the Build tab, I got the following message

Unsupported Java. 
Your build is currently configured to use Java 17.0.8 and Gradle 7.1.

Possible solution:
 - Use Java 16 as Gradle JVM: Open Gradle settings 
 - Upgrade Gradle wrapper to 7.2 version and re-import the project

The messages changed. The Gradle build worked on JDK17. This issue has been resolved.

Thout it shows other message, but I will follow it in another issue.
