    Short version. It is a Eclipse bug. The new version that fixes the problem is available by doing:

    Long version: I was only trying to clone. But one subtle behavior I noticed, and that’s perhaps a workaround for everyone, is that when you see a prompt for the password (the prompt without the check box to save it and without your user ID prefilled in the dialog), it’s really MPC that’s prompting for the password. If you enter a valid password, then EGit will not see a 401 response code, so EGit will not fill in your saved password when communicating with that server, hence the next EGit/JGit access will result in a 401 because the saved credentials are not being used. The tricky thing I noticed was that if I just hit escape or pressed cancel on the bogus password prompt, then EGit starts to work.

    There is a discussion in the Eclipse Forum: Eclipse Community Forum – Reply and a bug.

    This workarround is a suboptimal solution but at least worked for me. I had the old workspace with the old Eclipse Marte version. I tried to set the same credentials in the same way and unsurprisingly the old eclipse worked. But it also warned me that other application had modified the password store and asked me to changed them. Modifing it with the old eclipse made the Neon work. They seem to share the password store at least in Windows.
