Eclipse: The type {type} cannot be resolved. It is indirectly referenced from required .class files

The type {type} cannot be resolved. It is indirectly referenced from required .class files

In Eclipse, the cause of this problem is somehow deleted the SYSTEM JRE LIBRARY associated with your project.

Simple fix in Eclipse:
-Right Click Project you are working on from Package Explorer
-Go to Properties
-Go to Java Build Path from the right tree structure
-Go to Libraries Tab
-Choose Add Library Button
-Select JRE System Library
-Hit Next, the Radio button will prompt the Workspace default JRE, and let it be that way
-Hit Finish
