我想編譯使用maven protoc plugin和我在Cygwin內部構建的protoc可執行文件的協議緩衝區代碼。我無法從Cygwin或Windows命令行執行此操作。下面是我在Windows中運行它時得到的輸出，但從Cygwin運行時錯誤是相同的。我覺得這很奇怪，因爲如果問題是路徑翻譯，那麼我希望其中一個工作。可執行文件是用Cygwin的g ++編譯的事實可能會影響事物嗎？ （爲了說明問題，有問題的目錄確實存在。）在Windows中的協議錯誤
編輯：當我將maven從圖片中取出並手動調用protoc時，出現同樣的錯誤。
編輯2：我可以通過使用相對路徑或絕對路徑從Cygwin手動調用protoc來解決此問題（但代字符擴展不起作用）。從Windows使用相對或絕對路徑手動調用protoc繼續給出相同的錯誤。你建立使用Cygwin將取決於全面Cygwin環境，並會表現爲Cygwin的方案，無論您是如何執行他們

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).
