當我運行jarsigner時，它給出時間戳錯誤。離子發佈android apk簽名錯誤
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore android-release-unsigned.apk alias_name
錯誤：
No -tsa or -tsacert is provided and this jar is not timestamped. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2044-04-04) or after any future revocation date.
