Even though the Maven Eclipse plugin is retired, I still like using this plugin. There's sometimes one issue with the connection of projects in your Eclipse workspace.
By default, the Eclipse Plugin will create sub-projects for dependencies that exists in the reactor. If you don't want to work with the development code and prefer to use the deployed packages, you can still do so by disabling the project references like so:
mvn eclipse:eclipse -Declipse.useProjectReferences=false
