java.lang.Object cannot be resolved in Eclipse

Question

When I installed the latest installment in Mac OSX - the Mountain Lion - I experienced some problems getting Eclipse to work I also lost most of my Android developer files

Answer 1

Try the following and problem will go away

• Close the project and reopen it.

• Clean the project (It will rebuild the buildpath hence reconfiguring with the JDK libraries)

  OR

• Delete and Re-import the project and if necessary do the above steps again.
