SBT Project Publish to Maven Central - scala

Question

I'm in the process of publishing my project in GitHub as a jar file to the Maven central nexus repo and I followed all the steps as mentioned in this documentation page from SBT!
https://www.scala-sbt.org/release/docs/Using-Sonatype.html
But now when I ran
sbt publishSigned
command against my project, I get the following error:
[info] Done packaging.
[error] gpg: keyblock resource '/Users/joesan/.sbt/gpg/secring.asc': No such file or directory
[error] gpg: no default secret key: No secret key
[error] gpg: signing failed: No secret key

Looks like it is expecting some secrte file and I do not have it on the path. How to get around with this issue? Any ideas?

Answer 1

Find out where the missing file (secring.asc) is on your computer, you should have it
if you followed the instructions.
Then set the location in your ~/.sbt/gpg.sbt file:
pgpSecretRing := file("/tmp/secring.asc")
