[xwiki-devs] Dependency for pages modifications and XWiki context

Hi devs, I am developing a Java component that provides methods accessed through a script service. I need to modify XWiki pages, thus i need the context and, if i remember well, to add the "xwiki-platform-oldcore" dependency in the pom.xml file. Unfortunately maven cannot resolve the dependency, saying that "the artifact is missing". Someone can help me? Giordano.
