Jenkins：Barchart Jenkins Cascade 插件在发布构建期间抛出 JSchException

Question

我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

布局和模块项目已从配置的 git 存储库中检出，成员和级联项目已从布局项目正确构建。但是当我触发发布构建时（在项目页面上选择 "Cascade Release" 操作并单击 "Submit"），它会抛出以下异常：

我检查了目录 <jenkins_home>/.ssh/ 中的 known_hosts 文件，它包含异常中提到的指纹。以用户 jenkins 身份从命令行上的 git 存储库检出也可以正常工作。通过 Maven Release Plugin 发布时也不会发生这种情况。所以我想这一定是一个特定于插件的问题。也许配置错误！？

以下是我在服务器端看到的

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]

如有任何帮助，我们将不胜感激。

Answer 1

问题已解决，known_hosts 文件缺少远程主机 (myhost) 散列键与 git 用户 public 键的条目。通过将条目添加到文件中，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。
