I am trying to sign my commits, from Eclipse IDE, using GPG (as implemented by Git). I have generated the keys, updated the necessary configuration, bot on my computer and GitHub, but I can not get the process to work. Keep in mind that the commit process works ok from eclipse, as long as I do not enable signing (no problem with github setup).
If I enable the signing, in Eclipse, the process starts, it asks me for the password for the key but after that I get an error (showed in Eclipse details):
An internal error occurred

If I run the command C:\Program Files\Git\usr\bin\gpg.exe -bsau B08D503E442EBB5C --batch --no-tty --status-fd 2 --output - straight into GitBash, is it working ok, as I get the following output

What I tried so far:
- read a lot of data about Eclipse and signing, found nothing about this particular case
- is does not matter if git is using mingw64 or windows terminal
- it does not matter if I am using Git or Gpg4win
- it does not matter what algorithm I am using for the key (right now I am using RSA)
What am I suspecting: The Git/GPG installation is ok, there is a problem with the way Eclipse is reading the output from gpg.exe.
Any help will be appreciated.

After mode digging, I can see that the key is generared, but Eclipse says that is it invalid. Below is the error log from Eclipse.
