1. the error check was added for go-git, it was caused by the empty `.keep` file in the test fixtures.
2. use `PostFormValue` instead of `PostForm.Get` (`Get` needs to parse the form ahead)
3. fix incorrect container text (it should show "Images" in the header but not "OS/Arch")
4. align maven xml
5. fix closed PR color&icon
