svn merge：“目标路径不存在”

Question

对于我以前做过上百次的事情，我要拔出我的头发。我有一个子项目'a‘的发布候选分支，我们在最后时刻做了一些修改。现在我们已经释放了，我需要把它们带回后备箱。

我cd到我的主干工作副本，然后运行：

$ svn merge https://svn.server.com/svn/branches/a/release
svn: Target path '/branches/a/release' does not exist

什么……？分支和主干副本几乎都是肯定存在的。事实上，它们几乎是相同的。可能会遗漏什么？

下面是一些更多的上下文：

我还尝试使用--ignore-ancestry作为推荐的here，但尝试重新插入现有文件时发生冲突而失败。

如果我限制了我的版本号，合并就会起作用：

$ svn merge -r XXX:HEAD https://svn.server.com/svn/branches/a/release

其中XXX是我从主干复制/合并到分支的最后修订版号。
