Description Jay Shaughnessy 2009-04-06 15:03:00 UTC

If plugin A declares <depends plugin="B" useClasses="false"> and plugin B does not exist then plugin A's deployment fails.  This should be made more lenient as the deployment of A should still be valid and useful.  It may still be able to run independently and may still inject successfully into other, existing plugins.

Comment 1 Charles Crouch 2009-04-20 21:45:52 UTC

So, from greg, one use case for this feature would be 

(4:37:50 PM) ghinkle: i want to be able to inject my plugin into other people's plugins even if i'm not sure the user will have all of them
(4:41:03 PM) ccrouch: but will you really get inject just through the <depends> clause
(4:41:04 PM) ccrouch: ?
(4:41:47 PM) ghinkle: not just through it
(4:41:55 PM) ghinkle: but its needed if you want to inject
(4:42:14 PM) ccrouch: ok, necessary but not sufficient
(4:43:02 PM) ghinkle: e.g. the hibernate plugin could written to work in both jbossas and tomcat
(4:43:08 PM) ghinkle: (and probably should at some point)

Comment 2 Jay Shaughnessy 2009-04-22 15:37:45 UTC

This has been at least partially implemented.  A final solution may be more robust but rev3810 implemented leniency towards missing plugin dependencies and rev3816 prevented invalid deploymentService execution.

Comment 3 Jay Shaughnessy 2009-04-22 15:43:20 UTC

No more work on this defined at this time, so we'll resolve and create new jiras if and when we have more improvement work for plugin dependency

Comment 4 Pavel Kralik 2009-04-23 12:23:53 UTC

A hot-plug test with the Hibernate and JBossAS plugin. The Hibernate plugin registration failed first, but was successful after a while when the JBossAS plugin was registered. rev3819
