Required options being displayed as optional in SYNOPSIS --------------------------------------------------------------------------------------------- Key: FORGE-2088 URL: https://issues.jboss.org/browse/FORGE-2088 Project: Forge Issue Type: Bug Affects Versions: 2.12.1.Final Reporter: Ondrej Zizka Fix For: 3.0.0.Final Not sure if bug or feature, either way - I'd expect that feeding addon-remove an item from addon-list would remove it. Not the case: $ addon-list Currently installed addons: ... org.jboss.windup.qs:WindupQuickstart,2.0.0.Beta2 ...
