Provide custom repos for executing plugin

I am using with jaxb2-basics dependencies in building one of the project(Oozie). I want to use custom repos to download dependencies, but it makes use of default central repo and doesn't consider the ones passed in repositories or pluginRepositories tag ? How can we enforce use of custom repos ? Use of plugin can be found here : https://github.com/apache/oozie/blob/master/fluent-job/fluent-job-api/pom.xml
