Question

我已经创建了一个示例项目结构来测试Barchart Plugin。

-layout-project pom.xml
   -parent-module pom.xml
   -main-module pom.xml
   -dependency-module pom.xml

从配置的git repo中检出布局和模块项目，并从布局项目中正确构建成员和级联项目。但是当我触发发布版本（在项目页面上选择“Cascade Release”操作并单击“Submit”）时，它会引发以下异常：

我已经检查了目录known_hosts中的<jenkins_home>/.ssh/文件，它包含异常中提到的指纹。用户jenkins从命令行上的git repo中检出也没有任何问题。通过Maven Release Plugin发布时也不会发生这种情况。所以我猜它一定是插件特定的问题。也许错误配置！？

以下是我在服务器端看到的内容

Mar  7 18:33:03 myhost sshd[29240]: 
error: Received disconnect from 192.168.0.9 port 46217:3: com.jcraft.jsch.JSchException: 
UnknownHostKey: myhost. RSA key fingerprint is 20:be:e9:3a:44:3d:cf:a8:24:00:e3:29:ab:7f:73:c5 [preauth]
Mar  7 18:33:03 myhost sshd[29240]: Disconnected from 192.168.0.9 port 46217 [preauth]

任何帮助将不胜感激。

Answer 1

问题解决后，known_hosts文件错过了远程主机（myhost）散列键的条目以及git用户的公钥。通过将条目添加到文件，我可以使用命令ssh-keygen -l -E md5 -f .ssh/known_hosts验证它现在包含预期的指纹。
