从GitHub上无法下载子模块问题解决

  从GitHub下载同文trime输入法时因为墙的原因，导致无法链接到GitHub，特别是子模块没法下载。经过这几天的尝试找到一条解决方法如下：

# 1. 使用代理
git clone https://ghproxy.com/https://github.com/osfans/trime.git

# 2. 当中一些子模块不会下下来
# 修改.gitmodules文件，每条url加上https://ghproxy.com。如url = https://ghproxy.comhttps://github.com/BYVoid/OpenCC.git
[submodule "app/src/main/jni/OpenCC"]
	path = app/src/main/jni/OpenCC
	url = https://github.com/BYVoid/OpenCC.git
[submodule "app/src/main/jni/snappy"]
	path = app/src/main/jni/snappy
	url = https://github.com/google/snappy.git
[submodule "app/src/main/jni/boost"]
	path = app/src/main/jni/boost
	url = https://github.com/boostorg/boost.git
[submodule "app/src/main/jni/librime"]
	path = app/src/main/jni/librime
	url = https://github.com/rime/librime.git
	ignore = dirty
[submodule "app/src/main/jni/libiconv"]
	path = app/src/main/jni/libiconv
	url = https://github.com/osfans/libiconv-gnu.git
[submodule "app/src/main/jni/librime-lua"]
	path = app/src/main/jni/librime-lua
	url = https://github.com/hchunhui/librime-lua
	ignore = dirty
[submodule "app/src/main/jni/librime-lua-deps"]
	path = app/src/main/jni/librime-lua-deps
	url = https://github.com/hchunhui/librime-lua
	branch = thirdparty
[submodule "app/src/main/jni/librime-octagram"]
	path = app/src/main/jni/librime-octagram
	url = https://github.com/lotem/librime-octagram.git
[submodule "app/src/main/jni/capnproto"]
	path = app/src/main/jni/capnproto
	url = https://github.com/capnproto/capnproto.git
[submodule "app/src/main/jni/librime-charcode"]
	path = app/src/main/jni/librime-charcode
	url = https://github.com/rime/librime-charcode

# 3. 不断执行命令
git submodule update --init --recursive

  会有些子模块下不下来，我猜是墙的存在需要做很多检测，时间一长就断线了。因此要不断执行上面那句句，待墙检测完了就可以下下来。
  此时任然有一个问题就是boost子模块里还嵌套着子模块，boost中有些子模块下载下来的是空文件夹且无论执行多少次git submodule update --init --recursive都没用。原因是这些空文件夹中都有一个隐形的.git文件，将.git文件删除重新执行git submodule update --init --recursive就可以下载下来。此时cd 到boost中，具体操作如下：

jek@jek-virtual-machine:~/trime/trime/app/src/main/jni/boost$ find libs/ -name .git
libs/callable_traits/.git
libs/polygon/.git
libs/rational/.git
 ：
 ：
# 会出现很多.git文件，都删掉
jek@jek-virtual-machine:~/trime/trime/app/src/main/jni/boost$ find libs/ -name "*.git" | xargs rm -f

# 再执行就能将原来空的子模块文件夹
jek@jek-virtual-machine:~/trime/trime/app/src/main/jni/boost$ git submodule update --init --recursive
