检查本地副本时发生Buildbot svn错误

尝试使用Buildbot和SVN进行增量签出，但Buildbot始终先删除整个树。我相信这是因为日志中的代码2错误，但我找不到有关如何解决这些错误的任何信息：

stat: No such file or directory: **/home/mtrew/Documents/svn/card/branches/galrel1_13/.buildbot-patched
program finished with exit code 2
stat: No such file or directory: /home/mtrew/Documents/svn/card/branches/galrel1_13/.svn
program finished with exit code 2**
rm -rf /home/mtrew/Documents/svn/card/branches/galrel1_13
in dir /home/mtrew/Documents/buildbot/slave/galbuild (timeout 1200 secs)
watching logfiles {}
argv: ['rm', '-rf', '/home/mtrew/Documents/svn/card/branches/galrel1_13']

设置签出的cfg文件中的步骤是：

f_galbuild.addStep(steps.SVN(mode='incremental',
            method='fresh',
            repourl='http://titan/svn/sw/trunk/card/branches/galrel1_13',
            username = "XXXXX",
            password = "XXXXX",
            workdir = "/home/mtrew/Documents/svn/card/branches/galrel1_13"))

发件人：

因此，可能会发生某种冲突，因为您设置了一种增量模式，但使用的方法是完全的

SVN's incremental mode does not require a method.
