Maven defines three sets of life cycles, which are independent of each other. Clean life cycle pre clean: perform the work before cleaning;

Maven's core distribution package is less than 3MB. Maven will download and use plug-ins when necessary. For the plug-ins themselves, in order to reuse code, they can often complete multiple tasks. Maven's life cycle is bound to plug-ins to complete the actual construction tasks. Specifically, the phases of the life cycle are bound to the objectives of the plug-in to complete a specific construction task.
