Answer 1

The answer from "raj" is ok, thank you men! it is correct.

In addition to his solution i have to comment. Please save a copy of your .metadata

Take care when you delete the folder: .metadata/.plugins/org.eclipse.core.resources/.project

There is some folder called "RemoteSystemsTempFiles" and now you won't see the trouble when you start eclipse but you will other error when you close eclipse, because the folder "RemoteSystemsTempFiles" doesn't exist into .projects

So you will ned to copy your .metadataCOPIA/.plugins/org.eclipse.core.resources/.project/RemoteSystemsTempFiles to .metadata/.plugins/org.eclipse.core.resources/.project/RemoteSystemsTempFiles

So, the quick fix to the error "“Initializing Java Tooling.” in Eclipse on startup" for me is:

1- Copy the folder ".metadata" of your workspace in a copy. 2- Delete the folder ".metadata/.plugins/org.eclipse.core.resources/.project" 3- Close eclipse > You will get an error on closing eclipse. 4- Copy the folder .metadataCOPIA/.plugins/org.eclipse.core.resources/.project/RemoteSystemsTempFiles to .metadata/.plugins/org.eclipse.core.resources/.project/RemoteSystemsTempFiles 5- Star Eclipse and all is ok.
