[xwiki-devs] Editing the Xwiki core

These are all the xwiki-core-* jars that I have in the WEB_INF \ lib folder - xwiki-core-1.2-rc-1.jar *xwiki-core-1.4-SNAPSHOT.jar - This is the one I keep replacing with the new one everytime I build the core* xwiki-core-action-1.2-rc-1.jar xwiki-core-component-1.2-rc-1.jar xwiki-core-component-1.3-SNAPSHOT.jar xwiki-core-container-api-1.2-rc-1.jar xwiki-core-container-servlet-1.2-rc-1.jar xwiki-core-plexus-1.2-rc-1.jar xwiki-core-url-1.2-rc-1.jar Am I supposed to replace all of these? Thanks
