nThe pom.xml master file (cont.)
nThe <dependencyManagement> tag does not specify dependencies that master project depends on. Instead, it is used mainly by submodules.
nSubmodules
can specify a dependency on any of the entries within the <dependencyManagement> tag without specifying a specific version number.
nThis is useful for minimizing the number of
edits required when a tree
of projects changes dependency version numbers. In this case, the OpsImp project's version number is
specified using ${project.version}. This is a parameter that will be filled with the appropriate value during Maven execution.
