Can I change the alias of my key?

问题:

I signed my JWS application MemorizEasy with a key whose alias is: 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: 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: memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar

Yet that doesn't work. Trying another key with alias mjee it works. So could I change the alias of the key? If so, how? Otherwise, why wouldn't Maven accept my alias?

It is possible to duplicate a key in a keystore with the keyclone command of keytool:

keytool -keyclone -alias "your-very-very-long-alias" -dest "new-alias" -keypass keypass -new new_keypass -keystore /path/to/keystore -storepass storepass

The changealias command changes the alias for an existing entry:

keytool -changealias -alias "your-very-very-long-alias" -destalias "new-alias" -keypass keypass -keystore /path/to/keystore -storepass storepass
