Can run atlas-build, but can't package the Plugin

I’m getting an error when I try to either run atlas-mvn clean or atlas-mvn package:

I’m just trying to repackage a Jira 7 plugin that worked with an old SDK (7.x), and am now trying with the current SDK (8.0.16), but still Jira 7 for the plugin and it’s classes. I’ve already found a post about the change from maven-jira-plugin to jira-maven-plugin, and have made that change, but this error is still popping up with both the clean and package commands.
Oddly enough atlas-run works fine, and I can connect to that server, log in, etc…
Any idea what’s going on?

Looks like I’m a fool. The command to package was changed to atlas-package from atlas-mvn package. Works fine now…
