Explain Project Aggregation.

1.	Explain Project Aggregation.
Answer» Project Aggregation specifies the modules from the parent POM instead of specifying the parent POM from the module. As a result, the parent project is AWARE of its modules, and if a Maven command is issued against the parent project, the Maven command is also applied to the parent's modules. For Project Aggregation, you MUST accomplish the following: CHANGE the packaging of the parent POMs to "pom." Specify the modules' DIRECTORIES in the parent POM (children POMs).
