Docker build error by .gitmodules file

[fishmen]

When I built the dockerfile, I found the following error

Replace “git” to “https” in .gitmodules file to solve the problem and build successfully
here is the fixed .gitmodules.

[submodule "depends/gtest"]
	path = depends/gtest
	url = https://github.com/google/googletest.git
[submodule "depends/ate-pairing"]
	path = depends/ate-pairing
	url = https://github.com/herumi/ate-pairing.git
[submodule "depends/xbyak"]
	path = depends/xbyak
	url = https://github.com/herumi/xbyak.git
[submodule "depends/libsnark-supercop"]
	path = depends/libsnark-supercop
	url = https://github.com/mbbarbosa/libsnark-supercop.git
[submodule "depends/libff"]
	path = depends/libff
	url = https://github.com/scipr-lab/libff.git
[submodule "depends/libfqfft"]
	path = depends/libfqfft
	url = https://github.com/scipr-lab/libfqfft.git

Here is a dockerfile that is temporarily available.
