[jbosstools-issues] [JBoss JIRA] (JBDS-2390) How to customize JBT to be like JBDS

[Max Rydahl Andersen (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-2390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12735982#comment-12735982 ] 

Max Rydahl Andersen commented on JBDS-2390:
-------------------------------------------

This is not just about discovery url.

There is multiple things that JBT dynamically fetchs/adjust for.

Non-exhaustive list is:
 * list of project examples url's (done via plugins right now)
 * download url for server (not sure how that is done now)
 * central url 

And yes, I think setting this up in a plugin should be done - but extension points doesn't really work since if there are multiple of these - who wins ?

Thats why we've used the system property for now - since its global.

I was considering if we could simply just add to jbds central plugin an explict system property override in case the system property is not set already.


This would allow testing/QE to still override it.

> In JBDS, we override the discovery.url to set it to the value for JBDS extras site.
> However, this is done by hacking system properties. Instead, we could think of using the "discoveryProviderUrl" extension point in JBT.
> JBT would provide an extension to define this URL.
> JBDS would provide another extension to define this URL.
> Changing URL happens by updating the extension plugin.
> So JBT and JBDS would behave the same way when dealing with discovery, and we remove the system properties settings from JBDS. System proprty would still be available for testing only.
