I have started developing Xamarin.Forms applications in Visual Studio Enterprise 2015 as a beginner. When I build my solution I am getting an error like this:

The "AdjustJavacVersionArguments" task failed unexpectedly.

Severity Code Description Project File Line Suppression State Error The "AdjustJavacVersionArguments" task failed unexpectedly. System.NullReferenceException: Object reference not set to an instance of an object. at Xamarin.Android.Tasks.AdjustJavacVersionArguments.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.d__26.MoveNext() XamarinDemo.Android

What exactly this error means? Do I have a problem with my JDK version?

No. It didn't. I actually installed JDK 10 alongside 8 which I uninstalled and re-installed 8. - Olorunfemi Ajibulu

Problem was solved. I uninstalled JDK v9 and instead installed JDK v8. Later on, in Visual Studio I selected "Tools" -> "Options" and just scrolled down a little and found "Xamarin" -> "Android Settings" and changed the Java Development Kit Location with the path where the JDK v8 is located. After building the solution, error has been gone.
