AMPS 8.3.1 upgrade causing problems with atlas-debug command

I have upgraded my jira plugin dev environment to 8.20.5 and AMPS to 8.3.1. To support AMPS 8.3.1 Atlassian recommends upgrading the development environment’s Maven version to be 3.6.3 or later. I have followed instructions from the link to upgrade maven version to 3.6.3. Most of it seems to work, I am able to build my plugin but I’m having issues with the commands atlas-debug and atlas-package. On these 2 commands I get the following error:

{{ Unresolveable build extension: Plugin com.atlassian.maven.plugins:jira-maven-plugin:8.3.1 or one of its dependencies could not be resolved: Failure to find com.atlassian.maven.plugins:jira-maven-plugin:jar:8.3.1 in Central Repository: was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced → [Help 2]
[ERROR] Unknown packaging: atlassian-plugin @ line 14, column 16

Can anyone please help what am I doing wrong here?
