这里有一个方便的变化，我没有看到在常见问题中提到。可以通过指定文本编辑器返回当前消息进行编辑。

svn propedit svn:log --revprop -r N --editor-cmd vim

如果您正在使用eclipse之类的IDE，则可以使用这种简单的方法。

Right click on the project -> Team - Show history

右键单击提交的修订id，并选择“设置提交属性”。

您可以从这里修改您想要的消息。

实际上，您必须拥有存储库的管理权限(直接或间接)才能做到这一点。您可以配置存储库以允许所有用户执行此操作，也可以直接在服务器上修改日志消息。

请看这部分Subversion常见问题解答(重点是我的):

Log messages are kept in the repository as properties attached to each revision. By default, the log message property (svn:log) cannot be edited once it is committed. That is because changes to revision properties (of which svn:log is one) cause the property's previous value to be permanently discarded, and Subversion tries to prevent you from doing this accidentally. However, there are a couple of ways to get Subversion to change a revision property. The first way is for the repository administrator to enable revision property modifications. This is done by creating a hook called "pre-revprop-change" (see this section in the Subversion book for more details about how to do this). The "pre-revprop-change" hook has access to the old log message before it is changed, so it can preserve it in some way (for example, by sending an email). Once revision property modifications are enabled, you can change a revision's log message by passing the --revprop switch to svn propedit or svn propset, like either one of these: $svn propedit -r N --revprop svn:log URL $svn propset -r N --revprop svn:log "new log message" URL where N is the revision number whose log message you wish to change, and URL is the location of the repository. If you run this command from within a working copy, you can leave off the URL. The second way of changing a log message is to use svnadmin setlog. This must be done by referring to the repository's location on the filesystem. You cannot modify a remote repository using this command. $ svnadmin setlog REPOS_PATH -r N FILE where REPOS_PATH is the repository location, N is the revision number whose log message you wish to change, and FILE is a file containing the new log message. If the "pre-revprop-change" hook is not in place (or you want to bypass the hook script for some reason), you can also use the --bypass-hooks option. However, if you decide to use this option, be very careful. You may be bypassing such things as email notifications of the change, or backup systems that keep track of revision properties.

在Windows操作系统下，使用Tortoise SVN客户端:

右键单击项目文件夹，选择“显示日志” 在日志消息窗口中，右键单击修订并选择“编辑日志消息”。

如果它不起作用，可能是由于SVN在服务器上的设置方式，请在这里阅读其他响应。

我最近也接到了这个任务。

我们希望允许我们的程序员只修改他们自己的提交消息，并限制他们允许这样做的时间。我们决定允许他们修改当天提交的任何日志消息，以修复错字等。

在网上看了几个其他的例子后，我把它放在一起，我们在一个windows环境中，所以这是我们的pre-revprop-change.bat的内容:
