What is causing this error and how do I fix it?

Answer 1

Please follow the navigation as below:

Right Click(project) -> Java Build Path ->Libraries

Fix all the entries there with red cross mark in the front. You also may want to remove them and add them fresh using remove and add button in the right of the wizard.
