I installed the latest recommended version of Eclipse & the force.com IDE plugin , as described in the instructions (I installed version starting with "34."): https://developer.salesforce.com/page/Force.com_IDE_Installation

Then I created a force.com project for a sandbox environment , provided the user id , password and token, which downloaded the project contents from the server into eclipse.

But now if I make change to any class and try to save , I get the error

"Unable to connect to organization with given login credentials" .

So I tried to use the option "Deploy to server" and that works fine with the same username password and token. Dont know why.

I have selected the "Work Online" option. Also , if I try to do a "refresh from server" for the project, I get the same error so I tried to update the project properties. But when I fill in the username + password + token, and click on "Apply", it tries to re-fetch the project components, but gets stuck for some read only component, so there is a dialog box that asks if I want to skip all read-only warnings and if I say yes, it does nothing, the project doesn't get refreshed and I am stuck. If I click no, there are so many more read-only warning dialog boxes that follow, that I gave up.

I have no idea how to get around this issue, I tried installing older versions of eclipse, kepler , which I was using on my old laptop and was working fine, also juno, neon ,and that doesnt work, neither does installing any other version of the force.com IDE. Please help.

I found the solution. At least in my case, if I use the 32-bit eclipse, force.com IDE works with it, but not if I use the 64-bit eclipse(even though my OS is 64-bit).

  • I am not sure why it is not working for you. But for a side note I am using windows 10 64 bit and using eclipse(kepler version) without any issue. Not sure about your issue.
