Java – keytool – genkey error: keystore file does not exist

I try to create a new self certified keystore file

The commands I use are:

keytool -genkey -selfcert -dname "cn=My Name,ou=Orga unit" -alias selfcertified -keypass somepass -keystore keystore.jks -storepass anotherpass -validity 365

But I always get this annoying mistake:

keytool error: java.lang.Exception: Keystore file does not exist: keystore.jks

I don't understand why I got this mistake The above command should create a new keystore, so why does it complain about a non existing store?

Solution

Generating a key pair (and a new keystore) must create a self - signed certificate for the key as a separate operation

Namely

keytool -genkey -alias myKey -keystore store.jks
keytool -selfcert -alias myKey -keystore store.jks
