[jira] Updated: (MNG-396) attempt to create a shared and internal classloader for Maven
[ http://jira.codehaus.org/browse/MNG-396?page=all ]
Brett Porter updated MNG-396:
-----------------------------
Description:
currently, all plugins inherit everything in the Maven classloader hierachy, and we must filter those out so they end up with those versions.
We should minimise this, by separating the classloaders:
boot - classworlds
|
v
core - plexus
|
v
shared - anything that is passed from Maven's core to plugins (Eg project, plugin api, report api, ...)
|
+-> individual plugin classloader
|
+-> Maven internal classloader - add wagon, etc.
This allows invididual plugins to use newer or incompatible versions of JARs that Maven itself uses.
