我正在使用Android Studio，我想将部分kotlin / java项目转换为库。我将使用Gradle如here所述获取源。除了要使用具有ssh访问权限的私有git存储库。
我创建了没有密码短语的新ssh密钥对，并对其进行了测试，直接使用时一切正常。
我在settings.gradle中使用它：
sourceControl {
gitRepository('ssh://git@example-vcs/username/my-private-lib.git') {
producesModule('com.example:my-private-lib')
}
}
由于com.jcraft.jsch.JSchException: Auth fail，构建失败。它说Could not locate branch 'release'，尽管它确实存在。
这是完整的堆栈跟踪：
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':distTar'.
> Could not resolve all dependencies for configuration ':runtimeClasspath'.
> Could not locate branch 'release' for Git repository at ssh://git@example-vcs/username/my-private-lib.git.
* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Exception is:
org.gradle.api.internal.tasks.TaskDependencyResolveException: Could not determine the dependencies of task ':distTar'.

谢谢您的帮助！
答案 0 :(得分：2)
我也遇到了同样的问题，只想添加调查结果。
Auth fail表示JGit 无法找到和/或加载ssh密钥。
最简单的查找方法是将config文件添加到~/.ssh/目录中，其内容如下：
# Private GitLab server
Host <YOUR GIT HOST>
RSAAuthentication yes
IdentityFile ~/.ssh/<YOUR_SSH_KEY>
如果您具有有效的RSA密钥并且只是使用不同的名称（不是id_rsa），它可以提供帮助。
就我而言，我还有另一个例外：
Caused by: com.jcraft.jsch.JSchException: invalid privatekey: [B@e4487af
at com.jcraft.jsch.KeyPair.load(KeyPair.java:664)
这意味着您的ssh密钥不是RSA类型。 问题是-Gradle将JGit与jsch ssh实现一起使用，而不与Apache MINA一起使用。 而且jsch仅支持 RSA和DSA 密钥类型。
最新版本的OpenSSH（7.8及更高版本）默认情况下会以新的OpenSSH格式（ed25519或其他格式，但不是RSA）生成密钥。 因此，解决问题的简单方法就是使用以下命令生成正确的RSA密钥：
ssh-keygen -t rsa -m PEM
即使没有不必要的config文件，它也可以正常工作。
但是，当然，这是一种拐杖，我仍在尝试寻找一种配置Gradle的方法，或者说通过Gradle配置JGit以使用Apache MINA sshd实现并支持新的ssh密钥类型更好。
答案 1 :(得分：1)
今天早些时候，我们遇到了这个问题，并且得到了一些修正。如果您是从命令行构建的，则可以尝试如下设置GIT_SSH环境变量：
export GIT_SSH=ssh
如果这不起作用，您也可以尝试：
export GIT_SSH=/usr/bin/ssh
我不太确定为什么这样做，这可能与JGit的细微差别有关。
