[jira] Commented: (MNG-3766) toolchains not found in extensions

["John Casey (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-3766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=152062#action_152062 ] 

John Casey commented on MNG-3766:
---------------------------------

As I documented here:

http://docs.codehaus.org/display/MAVEN/Maven+2.1+Plugin+and+Extension+Loading+Design

The extension-loading mechanism in maven 2.x is horrible, and prone to all sorts of weird behavioral changes depending on things like the number of artifacts in the extension's transitive dependency closure. IMO it needs to be replaced with something sensible. If we don't take the time to fix this mess, it's just going to extend the confusion surrounding extensions (which are problematic for a lot of users I've talked to) into the realm of toolchains as well.

I'm definitely -1 for patching the extension-loading code to support toolchains the same way wagons are supported now.

> There's currently no way to plugin in new toolchains without placing them in M2_HOME/lib. For wagons to be available in extensions, the extension manager explicitly registers them - so I propose to do the same in 2.1.0-M2 for toolchains, and only support the Java toolchains in 2.0.9.
