svn - 强制旧版本成为最新版本 - SVN

Question

我有一个旧的修订版，效果非常好，我想撤销我在 SVN 中所做的过去的几个修订版。我怎样才能简单地删除这些修订并使 HEAD 成为特定的修订。这样，当我按下更新时，它会转到那个版本，而不是真正的当前版本？

Undoing Changes

Another common use for svn merge is to roll back a change that has already been committed. Suppose you're working away happily on a working copy of /calc/trunk, and you discover that the change made way back in revision 303, which changed integer.c, is completely wrong. It never should have been committed. You can use svn merge to “undo” the change in your working copy, and then commit the local modification to the repository. All you need to do is to specify a reverse difference:

$ svn merge -r 303:302 http://svn.example.com/repos/calc/trunk
U  integer.c

$ svn status
M  integer.c

$ svn diff
…
# verify that the change is removed
…

$ svn commit -m "Undoing change committed in r303."
Sending        integer.c
Transmitting file data .
Committed revision 350.
