7 Answers. Both plugins and dependencies are Jar files. But the difference between them is, most of the work in maven is done using plugins; whereas dependency is just a Jar file which will be added to the classpath while executing the tasks. For example, you use a compiler-plugin to compile the java files.
Keeping this in consideration, what's the difference between plug ins and dependencies?
Both plugins and dependencies are Jar files. But the difference between them is, most of the work in maven is done using plugins; whereas dependency is just a Jar file which will be added to the classpath while executing the tasks. For example, you use a compiler-plugin to compile the java files.
Similarly, what are plugins in Maven? Plugins are the central feature of Maven that allow for the reuse of common build logic across multiple projects. They do this by executing an "action" (i.e. creating a WAR file or compiling unit tests) in the context of a project's description - the Project Object Model (POM).
One may also ask, what are the dependencies in Maven?

- deploy – store in remote repository for sharing.
What is Maven snapshot?
A snapshot version in Maven is one that has not been released. The idea is that before a 1.0 release (or any other release) is done, there exists a 1.0-SNAPSHOT.
