Eclipse is giving me this error when I try to copy an object back to the Force.com server: "unable to perform synchronize check with remote server Invalid username, password, security token; or user locked out Your project may be out of sync."

This is my first try at using Eclipse, so it may not be set up right.

Can anyone help?


Edit: screenshot of trying to deploy: screenshot

Follow the steps below:

1. Right click on your project.
2. Go with Force.com-->Deploy to server.
3. You get the error here.
4. Re-enter the credentials - and if it still does not work you have 2 approaches.

2 Approaches:
1. Use any other user's credentials to see if it actually works.
2. Create a new project with a different name, make changes and deploy.

Ensure that you are using the proper security token! If unsure, generate a new one. This should help.

  • I'm doing that. It gave me a whole list of 284 deployment candidates. Why would that be? I only changed one object!

  • Have these components changed since the project was fetched locally? If they have, they need to be resync'd .

  • No - the only thing I changed is Contact.Object
