cygwin - Windows中的Protoc错误

我正在尝试使用maven protoc plugin和我在Cygwin中构建的protoc可执行文件来编译协议缓冲区代码。我无法从Cygwin或Windows命令行执行此操作。下面是我在Windows中运行时获得的输出，但从Cygwin运行时错误是相同的。我发现这很奇怪，因为如果问题是路径翻译，那么我希望其中一个能够工作。是否有可能使用Cygwin的g ++构建可执行文件可能会影响事情？（说明显而易见，有问题的目录确实存在。）

编辑：当我从图片中取出maven并手动调用protoc时，我得到了同样的错误。

编辑2：我可以通过使用相对或绝对路径从Cygwin手动调用protoc来解决这个问题（但是波形扩展不起作用）。使用相对路径或绝对路径从Windows手动调用protoc会继续产生相同的错误。

You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think).
