'Maven is downloading jars of its dependency
I have a pom file that has a single dependency. I want maven to download the dependency and wrap it in a new jar. However, when I run mvn clean package, it looks for the dependency, finds the dependency, and then looks at it's pom file and attempts to download all dependency of that dependency. How do I tell maven to not look at that dependencies' pom file and just download it?

Solution 1:[1]
You can use exclusions on the dependency to avoid the download of the transitive dependencies.
But usually, these transitive dependencies are needed to run your JAR, so you should be really be sure you don't need them.
