How to configure Gradle JDK in JetBrains Fleet?

To me, it looks like there may be an issue with the JDK version that is set in your JAVA_HOME setting/environment variables. You may wish to check there and/or configure the Fleet JDK settings for your project. — COleson, Oct 23 '22 at 02:37

By default, Fleet uses the JDK from your JAVA_HOME environment variable. Before proceeding, make sure it is configured in your environment. Otherwise, you can configure a custom JDK for your project as shown in the documentation.

Also, the "java.home" property in .fleet/settings.json user settings file should help.

Please see a documentation for more details.
