可能是什么问题和解决方案？

【问题讨论】：

标签： git bitbucket jgit spring-cloud-config

【解决方案1】：

显然，在克隆时org.eclipse.jgit 库在幕后使用系统配置的属性，其中一个属性是http.postBuffer。

它尝试将值转换为整数，如果值太大（或太小）则失败并出现上述超出范围错误。

我通过$ git config --get http.postBuffer 验证了该属性，它返回了值4572864000

我在 .gitconfig 文件中验证，它是全局值，所以我将值减小到 524288000

然后它就像魅力一样发挥作用。希望对面临同样问题的人有所帮助。

【解决方案2】：

对我来说有帮助的是将全局配置设置为 1MB：

git config --global http.postBuffer 1024
