一、概述

我最近在写一个android的项目。
软件：android studio、Android studio VCS integration（插件）
Android studio VCS integration插件：使用此插件结合github进行代码版本管理
近期出现的问题：
19:29:47.581: [DailyZHIHU] git -c core.quotepath=false push --progress --porcelain origin refs/heads/master:master
java.io.IOException: Authentication failed:
at org.jetbrains.git4idea.ssh.SSHMain.authenticate(SSHMain.java:298)
at org.jetbrains.git4idea.ssh.SSHMain.start(SSHMain.java:172)
at org.jetbrains.git4idea.ssh.SSHMain.main(SSHMain.java:137)
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
能够发现，在本地是被提交了的，但是在github上没有提交成功。结果想在本地check changes/commit的时候，却是no changes的。
截图如下：

二、解决办法

1、首先，确保各项设置全部正确（github连接成功、git.exe连接成功）

2、其次，将SSH executable：Built-in/Native选择成为Native

关于SSH executable：Built-in/Native的解释：
Specify the version of SSH to be used with Git.

• Native means that the native SSH will be used.
• Built-in means that the implementation provided by Android Studio will be used.

The native implementation might cause hangups on some platforms. In native case, you also might need to configure ssh-askpass for your platform to receive GUI prompts for passwords.
