IF you could please look at it and help me out.

Installing a different JDK is unfortunately not a workaround for me.  I am experiencing the same issue.  A real show stopper for me; as I am investing a lot of time to switch to Kotlin Gradle builld but now seeming there is Java/Gradle plugins that simply does not play nice.

Hi Andrey.  I have filed a problem and fixed the problem myself.  The warnings were a bit misleading at first...  but sorted it out.  Thank you.  Nothing to do with the version of JDK...  it was environment setup that was wrong in for gradle in my instance.

Hi Gawie, what was the environment setup for Gradle that was wrong? I am seeing the same errors in IntelliJ.

I ended up manually deleting IntelliJ cache folders. After that everything worked again.

~/Library/Caches/JetBrains/<product><version> on macOS
~/.cache/JetBrains/<product><version> on Linux
%LOCALAPPDATA%\JetBrains\<product><version> on Windows
