Since version 2.3 of the config-file-provider-plugin and jenkins 1.491, the settings.xml is handled correctly with the m2release plugin.
but maybe you are talking about the other release plugin...
I have never used it and I'm not sure what you mean by "are not available"?
Each file provided by the config-file-provider can be used in every build (not only with maven) in different ways, e.g.:
- in the build environment as "Provide Configuration files"
- copy it to the workspace with a build step
You can also give the copied script a final name and/or expose its name as a variable to reuse/reference it where ever you like.
