git submodule update --init --recursive

--recursive is important.

[dxzhan]

[bstaletic]

You forgot --init.

this is issue clear,but some one submodule download fail,other submodule stop download,maybe this is git issue.

[bstaletic]

Update YCM. We're not targeting go.googlesource.com any more.

[puremourning]

Probably the great firewall,.

[dxzhan]

i new clone this repo.
i try use Vundle plugin manger download it,but fail then i clone it by manual.

i search my local YouCompleteMe directory:
grep -i -n -r "googlesource" .

output this:
./third_party/ycmd/cpp/BoostParts/libs/filesystem/src/operations.cpp:28:// - https://android.googlesource.com/platform/bionic/+/a34817457feee026e8702a1d2dffe9e92b51d7d1/docs/32-bit-abi.md#32_bit-abi-bugs
./third_party/ycmd/cpp/BoostParts/boost/core/demangle.hpp:34:// (https://android.googlesource.com/platform/ndk/+/master/sources/cxx-stl/gabi++/), which does not implement

• Do this
• git submodule sync
• git submodule update --init --recursive

[dxzhan]

i in china,great firewall filter googlesource link
i comment .gitmodules about go configuration and remove cregex directory.
git submodule update --init --recursive and recompile success.
it work!

[jinzk]

after i run the following command

git submodule sync
git submodule update --init --recursive

it show me the error information

error: Server does not allow request for unadvertised object cc538bb6d0fcf0a6411537a5522d13cc9b86789d
Fetched in submodule path 'third_party/cregex', but it did not contain cc538bb6d0fcf0a6411537a5522d13cc9b86789d. Direct fetching of that commit failed.

it looks like that the git repository

https://github.com/ycm-core/regex.git

has not a commit id cc538bb6d0fcf0a6411537a5522d13cc9b86789d

Need to run git submodule sync —recursive

[Goku-San]

Just had the same issue..
Just wanted to say thanks @bstaletic

What I did was, in youcompleteme directory, git submodule sync --recursive and git submodule update --init --recursive

[jiapengwen]

• Do this
• git submodule sync
• git submodule update --init --recursive
