Maven Eclipse Plugin
The Eclipse Plugin is used to generate Eclipse IDE files (*.classpath, *.wtpmodules and the .settings folder) for use with a project.
The Maven Eclipse Plugin has five goals:
is used to add the classpath variable MAVEN_REPO to Eclipse which points to your local repository.
is used to delete the files used by the Eclipse IDE.
generates the Eclipse configuration files.
copies all Eclipse plugins from an installation directory to the local repository, generating POMs for each.
installs all resolved project dependencies of a particular type (usually 'eclipse-plugin') into the specified Eclipse installation directory.
