I am looking for some advice about how to get over the following maven
problem which I have tripped across while trying to deploy the 10.15.1.3
artifacts to the Nexus staging repository.
The deployment of derby.war is failing with the error included at the
end of this message. I am not a maven expert and the advice on the web
does not help me move this forward. I have tried running the following
command...
mvn -Dgpg.passphrase="cat gcn gov vtd nth amc" deploy
...using JDK 6, 7, 8, 9, and 11. I get a different error with JDK 6.
With the other JDKs, I get the error at the end of this message. My
naive misunderstanding of what's going on is that, for reasons which are
hidden in the secret maven handshakes, maven is trying to build a war
file and failing--even though we don't want maven to build a war file,
we just want to upload derby.war to the repository.
I hope that someone can help me push through this error. Otherwise, the
only options I see are:
1) Delay the publication of 10.15.1.3 until I have learned enough maven
to be able to fix this. That is an unbounded problem. Since this has to
happen in my spare time and I am busy, this option could take weeks.
2) Remove the deployment of derby.war. People who want the war file can
get it from the Derby distributions. I have never used the war file
myself, so I wouldn't miss it.
I am leaning toward option 2.
I would appreciate any advice which the community can give me.
Thanks,
-Rick
