Subject [jira] [Commented] (MNG-5227) The 'optional' flag of a dependency should be manageable.
Date Wed, 03 Feb 2016 18:53:39 GMT

    [ https://issues.apache.org/jira/browse/MNG-5227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15130874#comment-15130874

Christian Schulte commented on MNG-5227:
----------------------------------------

Please see the Aether bug this issue is linked to. It's not changing the way dependency management
works. It's just changing the order in which dependency selection and dependency management
is performed. Instead of first deciding to select a dependency and then applying management
(updating the selected dependency), it needs to first apply management to a dependency to
then use the managed state to decide if that dependency is to be selected. So if you manage
the scope to test, a transitive dependency will correctly no longer be selected and if you
manage the optionality to 'true', a transitive dependency will also correctly no longer be
selected.
