This repository demonstrates how you can use the goal eclipse-settings of the eclipse-settings-maven-plugin (GitHub) to synchronize the eclipse-settings files between multiple projects.
The *.prefs files stored inside a maven artifact are extracted into each .setting folder of each project using the maven plugin.
This repository provides some example projects that use the maven plugin. They are located in the example-use folder.
Read more on the project home page.
