下面就是一些default lifecycle的phase：
validate
initialize
generate-sources
process-sources
generate-resources
process-resources
compile compile
process-classes
generate-test-sources
process-test-sources
generate-test-resources
process-test-resources
test-compile
process-test-classes
test
prepare-package
package
pre-integration-test
integration-test
post-integration-test
verify
install
deploy
简单的可以理解为插件的执行顺序。
