Maven Coordinates
groupId:artifactId:version is the minimum amount of information to fully and unequivocally identify an artifact, and constitute an address and a timestamp. This information is referred to as maven coordinates. More details about each component below.
Group ID
An unique identifier for a project. Specified as <groupId> at the top of the POM file.
groupId: This is generally unique amongst an organization or a project. For example, all core Maven artifacts do (well, should) live under the groupId org.apache.maven. Group ID's do not necessarily use the dot notation, for example, the junit project. Note that the dot-notated groupId does not have to correspond to the package structure that the project contains. It is, however, a good practice to follow. When stored within a repository, the group acts much like the Java packaging structure does in an operating system. The dots are replaced by OS specific directory separators (such as '/' in Unix) which becomes a relative directory structure from the base repository. In the example given, the org.codehaus.mojo group lives within the directory $M2_REPO/org/codehaus/mojo.
