There’s background information about this post in my previous post. I’ve been using the Eclipse Dash License Tool on itself.
$ mvn dependency:list | grep -Poh "\S+:(system|provided|compile)$" | java -jar licenses.jar - Querying Eclipse Foundation for license data for 7 items. Found 6 items. Querying ClearlyDefined for license data for 1 items. Found 1 items. Vetted license information was found for all content. No further investigation is required.
