什么,"致命:错误计算合并基础"是什么意思？

Question

我已经让詹金斯跑了大约一年了.它构建master,rc*和production分支.在每次提交时,它执行git克隆,进行bundle安装,运行迁移等.它一直在完美地工作.最近,它失败了,我得到以下追溯:

紧随其后显示如下:

此提交错误也令人困惑,因为所有分支都包含它.

究竟是什么,"错误计算合并基数意味着什么？" 为什么我收到丢失的提交消息？

任何见解都将非常感激.

谢谢.

git fsck:

Checking object directories: 100% (256/256), done.
Checking objects: 100% (3203/3203), done.

在我的Jenkins配置中,我的git插件配置设置为:

1. 在构建之前擦除工作区
2. 使用浅克隆

我正在使用Jenkins,ver.1.528.

Answer 1

根据上面的twalberg的评论,禁用浅克隆解决了这个问题.建立所有分支机构并完成工作.
