Suppose I have created an empty Maven project in Eclipse. What is the shortest way to observe Maven's ability of automatic jar downloading and dependency checking? For example, I need to use Swing or log4j library. How can I add them without thinking where to download?
Add a dependency, for example, Log4J 1.2.16; it will be downloaded automatically, along with its dependencies. Then check in your home directory's .m2/repository directory.
