Difference between maven scope compile and provided for JAR packaging

by

From the Maven Doc:

  • compile

    This is the default scope, used if none is specified. Compile
    dependencies are available in all classpaths of a project.
    Furthermore, those dependencies are propagated to dependent projects.

  • provided

    This is much like compile, but indicates you expect the JDK or a
    container to provide the dependency at runtime. For example, when
    building a web application for the Java Enterprise Edition, you would
    set the dependency on the Servlet API and related Java EE APIs to
    scope provided because the web container provides those classes. This
    scope is only available on the compilation and test classpath, and is
    not transitive.

Recap:

  • dependencies are not transitive (as you mentioned)
  • provided scope is only available on the compilation and test classpath, whereas compile scope is available in all classpaths.
  • provided dependencies are not packaged
