Maven2 life cycle

Maven2 phase (life cycle) description:
Maven2 has three independent life cycles, and Maven commands are also based on these life cycles.
1.clean: Clean up previously built components, which are divided into the following three sub-stages:
　　a.pre-clean Perform some work that needs to be done before cleaning.
　　b.clean clean up the files generated by the last build
　　c.post-clean perform some work that needs to be done after
cleaning The phases are as follows:
　　a.validate verify the project is correct and all required information is available
　　b.initialize initialize the build state
　　c.generate-sources generate all the source code used for compilation
　　d.process-sources process the source code
　　e .generate-resources Generate the resources contained in the package
　　f.process-resources Copy and process the resources to the target directory, ready for packaging
　　g.compile Compile the main source code of the project
　　h.process-classes Perform the files generated by the compiler Post-processing
　　i.generate-test-sources Generates all test source code for compilation
　　j.process-test-sources Processes test source code
　　k.generate-test-resources Resources needed to create tests
　　l.process-test-resources Copy and process resources to the test target directory
　　m.compile Compile the test source code to the target directory
　　n.process-test-classes Post-process the files generated by compiling the test source code
　　o.test Use the appropriate unit The test framework runs tests that should not be packaged or deployed
　　p.prepare-package does everything needed to prepare it for packaging, which often results in a processed version of the package that has not been packaged
　　q.package uses the set way to package the compiled files
　　r.pre-integration-test perform some necessary operations before the execution of the integration test
　　s.integration-test process and deploy the package to the integration test environment for testing
　　t.post-integration-test to integrate Tests are post-processed
　　u.verify performs all checks to ensure the package is correct and meets quality requirements
　　v.install installs the package to the local repository, provides dependencies for other local projects i
　　w.deploy publishes the package, copies the final package to the remote repository 3.site
: Build and publish project site
　　a.pre-site Pre-preparation
　　b.site Generate project site documentation
　　c.post-site Post-processing
　　d.site-deploy Deploy site to server
