I have the "Java Source Base Plugin" error as well. Had no idea how to report that error or what it was in fact. I will be listening to this thread!
I get the error on booting NetBeans, don't know how to update this version. Downloaded netbeans.exe not built. Windows 10 Preview Evaluation Build 17704.rs Latest.

When I install the RC1 binaries and go to update plugins I get: This happens when using a Java 8 SDK and a Java 10 SDK. Only difference between 8 and 10 is that NetBeans does not show Ant as an update with Java 8. Otherwise both want Java Source Base plugin installed. What is and where is Java Source Base plugin.
