Scott Marlow commented on JASSIST-261:
--------------------------------------
hmm, now I see:
{code}
[INFO] --- maven-gpg-plugin:1.4:sign (sign-artifacts) @ javassist ---
gpg: no default secret key: unusable secret key
gpg: signing failed: unusable secret key
{code}
To see the above failure, I did:
{quote}
git pull upstream master --tags
git checkout rel_3_21_0_ga
mvn -P centralRelease javadoc:jar deploy
{quote}
I think that I need to renew my public key as it expired on 2016-05-07. I'll look into that and try again :)
