What are the phases of the maven default lifecycle?

The phases of the default (build) mavenSW lifecycle are listed at http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle. I have listed them again here:

Maven Default Lifecycle Phases

  1. validate
  2. generate-sources
  3. process-sources
  4. generate-resources
  5. process-resources
  6. compile
  7. process-classes
  8. generate-test-sources
  9. process-test-sources
  10. generate-test-resources
  11. process-test-resources
  12. test-compile
  13. test
  14. prepare-package (maven 2.1+)
  15. package
  16. pre-integration-test
  17. integration-test
  18. post-integration-test
  19. verify
  20. install
  21. deploy

Notice that there are actually 21 phases of the default lifecycle listed. The "prepare-package" phase, however, won't be used until maven 2.1+. Since I am running 2.0.8 (the latest version at the time of this writing), this phase is not available to me.

There are a couple key concepts to be aware of with maven lifecycles. First off, if we call a particular phase via a maven command, such as "mvn compile", all phases up to and including that phase will be executed. So, in the case of "mvn compile", we would actually go through the validate, generate-sources, process-sources, generate-resources, process-resources, and compile phases. The second main concept to be aware of in regards to lifecycles is that, based on the packaging of a project (jar, warW, earW, etc), different maven goals will be bound to different phases of the maven lifecycle.

Let's demonstrate the phases of the maven default lifecycle. One way to do this is to bind the antrun:run goal to the various phases of the maven default lifecycle, and to output a message using the AntSW echo task. Here, I created a pom.xml file that will output a message for each phase of the default lifecycle.

pom.xml file that binds antrun:run to default lifecycle phases

Now, let's try a "mvn deploy" on the project containing the above pom.xml file. The deploy phase is the last phase of the default lifecycle. Since it is the last phase, all phases of the lifecycle will be executed.

From the output, notice that all phases of the lifecycle are executed. Notice that the "prepare-package" phase (14 of 21) does not occur since I'm not using maven 2.1 (since it hasn't been released at the time of this writing).
