Description

Some versions and configurations of GPG want to pop an interactive UI, which the maven-gpg-plugin cannot handle. This appears in the log, before Maven quits without much advice:

*gpg: WARNING: "--no-use-agent" is an obsolete option - it has no effect
"gpg: signing failed: Inappropriate ioctl for device"

The remedy is for the user to do something with gpg on the command line before going into mvn-release:prepare. Something that will allow gpg to remember (for a period of time) the passphrase entered in that interactive UI, that the maven invocation of gpg can take advantage of afterwards.

Historically there was a gpg option '--no-use-agent', but not all gpg implementations support that today, not will going forwards as it is being removed.

Suggestion: On command error, System.out.println the remedy above, perhaps even suggesting the command to run:

gpg --use-agent --armor --detach-sign --output $(mktemp) pom.xml
