官方提供:  keytool -genkey -v -keystore %userprofile%\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload

結果:[Storing %userprofile%\upload-keystore.jks]

keytool error: java.io.FileNotFoundException: %userprofile%\upload-keystore.jks (系統找不到指定的路徑。)

解決方法:

刪掉路徑!

  keytool -genkey -v -keystore %userprofile%\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload

可成功產生JKS檔案，位置在專案目錄下。

  keytool -genkey -v -keystore upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload
