Answer 1

Try updating your JDK. I use jdk1.8.0_121. Just setting the configuration property http.sslVerify=false in .gitconfig is enough.

Answer 2

This should be a comment, but for some stupid reason i need to have a reputation to make a comment...

Same problem here.

My git server have a self-signed certificate.

The certificate name (CN) have the same name as the hostname i use to connect to it.

I had put the configuration property "http.sslVerify=false" in .gitconfig.

When i try to clone (using https), Eclipse connects to the repository, gets the repository information, shows the "master" branch, starts to clone (it shows the progress bar), receive the objects, but throws an Exception at the end (exception below), and didn't clone the repository (see the images below).

There is probably a bug here, since it can read the repository to get its information and files, but cannot finish the whole process.
