Invalid source release when using Intellij​

When using intellij after upgrading project JDK and settings, you may still see Cause: error: invalid source release: 17, Cause: error: invalid source release: 21 etc. You need to update the JVM used by gradle as well under Settings -> Build, Execution, Deployment -> Build Tools -> Gradle -> Gradle JVM.
