How to change the alias of a key within a keystore?
提问by simpatico
I signed my JWS application MemorizEasywith a key whose alias is:
我使用别名为的密钥签署了我的 JWS 应用程序MemorizEasy：
memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar
I don't remember why I chose such a long alias. I suspect it was memo only, but in my project settings I have:
我不记得为什么我选择了这么长的别名。我怀疑这只是备忘录，但在我的项目设置中，我有：
jnlp.signjar.alias=memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar
I'm now updating the application and using maven I need to specify the alias as:
我现在正在更新应用程序并使用 maven 我需要将别名指定为：
<keystorealias>memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar
</keystorealias>
Yet that doesn't work. Trying another key with alias mjeeit works.
然而这行不通。尝试使用别名的另一个键mjee可以工作。
So could I change the alias of the key? If so, how? Otherwise, why wouldn't Maven accept my alias?
那么我可以更改密钥的别名吗？如果是这样，如何？否则，Maven 为什么不接受我的别名？

It is possible to duplicate a key in a keystore with the keyclonecommand of keytool:
可以使用以下keyclone命令在密钥库中复制密钥keytool：
keytool -keyclone -alias "your-very-very-long-alias" -dest "new-alias" -keypass keypass -new new_keypass -keystore /path/to/keystore -storepass storepass
The changealiascommand changes the alias for an existing entry:
该changealias命令更改现有条目的别名：
keytool -changealias -alias "your-very-very-long-alias" -destalias "new-alias" -keypass keypass -keystore /path/to/keystore -storepass storepass
For those that want to be prompted to enter password just remove the respective password flags (changealiasexample):
对于那些想要提示输入密码的人，只需删除相应的密码标志（changealias示例）：
keytool -changealias -alias "your-very-very-long-alias" -destalias "new-alias" -keystore "/path/to/keystore"
