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

Snjezana Peco commented on JBDS-2390:
-------------------------------------

There are already the standard external download URL within the code that can be overridden using the jboss.runtime.directory.url system property.
I don't see how an extension point would help since we can create only one ext. point. It also can't be changed without changing the code (plugin.xml).
Adding a plugin that would set a system property is, in my opinion, a good idea. I suppose, the plugin would be included in JBT/JBDS only when testing, not in the final distribution. 

JBoss Central works in a similar way. We have hardcoded discovery location that can be overridden with the jboss.discovery.directory.url system property.

As to the project examples
Project examples can be added in four ways:
- using an extension point
- using user sites
- using a system property
- adding .project_example.xml to some JBoss AS server home directory

> 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.
