This plugin lets you use builders, publishers and SCM settings from another project.
A short set up guide
Set up a template project that has all the settings you want to share. E.g. you could create one with no SCM filled in, but with all the builders and publishers you want for all your projects. Its best to mark this project as disabled, since you are not actually going to run it.
Then set up a concrete project. Configure the SCM as you want. Then select 'use all the publishers from this project' and pick the template project. Ditto for the builders.
It may be using some plugins in ways that were not intended. Compatibility with all plugins is not guaranteed.
It does not support project actions. That means that links that should be on the project page (e.g. 'latest test results') will not be there.
