升级Jenkins 2.387.2后，SCM加载Jenkinsfile的流水线报Git目录错误

升级Jenkins到2.387.2版本后，所有通过Git SCM加载Jenkinsfile的流水线均出现如下错误：

hudson.plugins.git.GitException: Command "git config remote.origin.url git@github.com:jenkinsci/pipeline-examples.git" returned status code 128:

关键信息 #

• 异常触发条件：仅通过Git SCM加载Jenkinsfile时报错，直接在任务内编写流水线代码时Git操作完全正常
• 插件版本：Git client plugin (git-client) 4.2.0，Git plugin (git) 5.0.2
• 运行环境：Kubernetes集群，Agent以Pod形式运行
• 复现情况：新建流水线任务也能复现该问题

更新记录 #

更新1 #

测试同版本（2.387.2）的全新Jenkins实例，运行相同任务可正常执行，说明问题仅存在于现有Jenkins实例中。

更新2（临时解决方案） #

该问题表现与jenkinsci/helm-charts仓库的Issue #728类似，将Jenkins基础镜像从Debian版本的jenkins/jenkins:lts-jdk11切换为CentOS版本的jenkins/jenkins:lts-centos7-jdk11后问题解决。目前暂未明确两类镜像在EFS文件系统下表现差异的具体原因。
