[英]Unzip file issue in Pentaho-spoon
我正在嘗試解壓縮作業中的文件,一切正常,直到 zip 中的文件名包含一些特殊字符,例如“á、é、í、ó、ú”。 當 zip 中的文件名包含這些字符時,我收到一個錯誤和此日志:
Unzip file - ERROR (version 8.1.0.0-365, build 8.1.0.0-365 from 2018-04-30 09.42.24 by buildguy) : Could not unzip file [file:///C:/pentaho/data/example.zip]. Exception : [MALFORMED]

我該如何解決這個問題?
我正在附上作業的圖像:解壓縮文件作業
鈀。 我已經看過這里和其他論壇。 謝謝
我找到了解決方案,可以幫助某人,所以我發布了它。
