cocos2d-x-3.17 を git clone

cocos2d-x レポジトリをクローンして、[オフィシャルサイトからダウンロード](http://www.cocos2d-x.org/download)できる cocos2d-x-3.17.zip の内容を再現してみた

# 目的

1. レポジトリとオフィシャルダウンロードの差を確認（もしあれば）


# 環境

1. macOS 10.13.5 (英語)
2. git-2.17.1 (brew)


# 手順

1. 基本的に https://github.com/cocos2d/cocos2d-x の README.md に従う


2. git レポジトリをクローン

		$ git clone https://github.com/cocos2d/cocos2d-x.git
		Cloning into 'cocos2d-x'...
		remote: Counting objects: 441326, done.
		remote: Compressing objects: 100% (8/8), done.
		remote: Total 441326 (delta 0), reused 2 (delta 0), pack-reused 441318
		Receiving objects: 100% (441326/441326), 894.17 MiB | 7.73 MiB/s, done.
		Resolving deltas: 100% (298326/298326), done.
		Checking out files: 100% (5997/5997), done.

		$ cd cocos2d-x


3. `cocos2d-x-3.17` タグをチェックアウト

		$ git checkout cocos2d-x-3.17
		Note: checking out 'cocos2d-x-3.17'.

		You are in 'detached HEAD' state. You can look around, make experimental
		changes and commit them, and you can discard any commits you make in this
		state without impacting any branches by performing another checkout.

		If you want to create a new branch to retain commits you create, you may
		do so (now or later) by using -b with the checkout command again. Example:

		  git checkout -b <new-branch-name>

		HEAD is now at 5c381d8ee6 sync Chinese release notes with English improvements (#18832)


4. 外部ライブラリをダウンロード

		$ python download-deps.py
		=======================================================
		==> Prepare to download external libraries!
		==> version file doesn't exist
		==> Ready to download 'v3-deps-142.zip' from 'https://github.com/cocos2d/cocos2d-x-3rd-party-libs-bin/archive/v3-deps-142.zip'
		==> WARNING: Couldn't grab the file size from remote, use 'zip_file_size' section in '/Users/kenichi/butaimeguri/cocos2d-x/external/config.json'
		==> Start to download, please wait ...
		==> Downloading finished!                                                    
		==> Extracting files, please wait ...
		==> Extraction done!
		==> Cleaning cocos2d-x/external folder ...
		==> Copying files...
		==> Cleaning...
		==> Would you like to save 'v3-deps-142.zip'? So you don't have to download it later. [Yes/no]: no

	1. `3.16` の `v3-deps-136` から `v3-deps-142` に更新されてる


5. git submodule をクローン

		$ git submodule update --init
		Submodule 'tests/cpp-tests/Resources/ccs-res' (git://github.com/dumganhar/ccs-res.git) registered for path 'tests/cpp-tests/Resources/ccs-res'
		Submodule 'tools/bindings-generator' (git://github.com/cocos2d/bindings-generator.git) registered for path 'tools/bindings-generator'
		Submodule 'tools/cocos2d-console' (git://github.com/cocos2d/cocos2d-console.git) registered for path 'tools/cocos2d-console'
		Submodule 'web' (git://github.com/cocos2d/cocos2d-html5.git) registered for path 'web'
		Cloning into '/Users/kenichi/butaimeguri/cocos2d-x/tests/cpp-tests/Resources/ccs-res'...
		Cloning into '/Users/kenichi/butaimeguri/cocos2d-x/tools/bindings-generator'...
		Cloning into '/Users/kenichi/butaimeguri/cocos2d-x/tools/cocos2d-console'...
		Cloning into '/Users/kenichi/butaimeguri/cocos2d-x/web'...
		Submodule path 'tests/cpp-tests/Resources/ccs-res': checked out '5d65db4c5f18c0df1305ff32b076425ab228cc4a'
		Submodule path 'tools/bindings-generator': checked out '2aa9b21f11bf514ca80f243b21750e8c7c28f05e'
		Submodule path 'tools/cocos2d-console': checked out '958531ee955b08f9b388847b7ab9eb0bb468c18c'
		Submodule path 'web': checked out 'e79acd062363818af809c51804083a5989a9aedc'

	1. `3.16` の時にあった `plugin` が無くなってる

6. cocos2d-console をダウンロード

		$ (cd tools/cocos2d-console; python download-bin.py)
		=======================================================
		==> Preparing to download console binaries!
		==> version file doesn't exist
		==> Ready to download 'v3-console-16.zip' from 'https://github.com/cocos2d/console-binary/archive/v3-console-16.zip'
		==> WARNING: Couldn't grab the file size from remote, use 'zip_file_size' section in '/Users/kenichi/cocos2d-x/tools/cocos2d-console/config.json'
		==> Starting to download, please wait ...
		 ==> Downloading finished!al: 38343K, Percent: 98.13%, Speed: 9808.06 KB/S 
		==> Extracting files, please wait ...
		==> Extraction done!
		==> Copying files...
		==> Cleaning...
		==> Delete 'v3-console-16.zip' file? It may be reused when you execute this script next time! (yes/no): yes

    1. `3.16` と同じ `v3-console-16` のまま（更新されてない）
    2. この手順は README.md には書いてない
    3. `cd` しないで直接 `tools/cocos2d-console/download-bin.py` を実行するとエラー： `DistutilsFileError: cannot copy tree 'console-binary-3-console-16': not a directory`
    4. さっきはダウンロードした zip を消すのが ```no``` だったけれど、今度は ```yes```


# 確認

1. オフィシャルサイトから `cocos2d-x-3.17.zip` をダウンロードして、比較

		$ cd ..
		$ unzip cocos2d-x-3.17.zip
		$ diff -r cocos2d-x cocos2d-x-3.17
		Only in cocos2d-x: .git
		Only in cocos2d-x/tests/cpp-tests/Resources/ccs-res: .git
		Only in cocos2d-x/tools/bindings-generator: .git
		Only in cocos2d-x/tools/cocos2d-console: .git
		Only in cocos2d-x/web: .git

    1. `.git` ディレクトリ以外に差異はない
