问题分析与解决 #

报错核心是Groovy解析时找不到git属性，原因是Jenkinsfile中checkoutGit的credentialsId参数值git-ssh未加引号。Groovy会将无引号的git-ssh视为表达式，尝试查找名为git的变量并执行减法操作，而当前上下文不存在git变量，因此抛出MissingPropertyException。

修复方法：将git-ssh用单引号或双引号包裹，明确为字符串类型：

checkoutGit(
    credentialsId: 'git-ssh', // 添加引号
    remoteUrl: 'ssh://git.t.com:123',
    refspec: '+$GERRIT_REFSPEC:$GERRIT_REFSPEC',
    branch: 'main'
)
