'.classpath'文件中的某个'svn diff'给出了以下输出。我看不到工作副本（+）和原始副本（ - ）之间有什么区别（是吗？）。问题是我没有更改这些文件（即我没有尝试更改项目的构建路径）但它们似乎在构建期间被修改。我使用STS 3.3.0.RELEASE，没有'svn'插件。我确实使用maven插件进行eclipse构建。
如果他们没有被触及，那就太好了。有没有办法，我可以保证这个吗？另一方面，如果我的'.classpath'文件没有被触及，那么为什么'svn diff'给我这个输出？
感谢。

@JimLewis和其他人在问题下面的评论中提出的怀疑确实如此。将所述命令的输出保存到文件中并对该文件执行cat -v会产生以下输出：

原始的'.classpath'是在Windows机器上生成的，它使用CRLF换行符，而我的unix机器上的maven则用LF换行符替换它们。同样建议，svn:ignore或'svn revert'可用于处理此类案件。
