How to invoke maven default lifecycle

If i call

mvn clean install

maven knows that clean is a lifecycle and install is a phase of the default lifecycle

if i call

mvn deploy

maven will execute all phases of the default lifecycle sequentially.

Is there a way to call the default lifecycle by giving a lifecyle name (instead of executing the last phsae of the lifecycle)?

EDIT: So the question is: is there a command

mvn lifecyclename

that start execution of the default lifecycle?

As far as I know you cannot execute an isolated lifecycle phase.

But you can execute an isolated plugin goal . 

mvn deploy:deploy

That won't trigger any plugin execution tied to deploy phase. But you can always add more plugin execution to the command line. So I better go with a profile skipping all plugins executions.

If you want to execute a myplugin:mygoal that was tied to deploy phase then

mvn myplugin:mygoal deploy:deploy

But the configuration of the execution must be in the cli.

But you better skip plugin executions that you do not want. only skip test and integration-test in command line. But you can achieve that with a profile that sets the configuration for the default cycle to skip.

<profiles>
  <profile>
    <id>skip</id>
      ...
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.5.1</version>
            <configuration>
            <skip>true</skip>
            </configuration>
          </plugin>
  ...

And then summon with

mvn deploy -Pskip

There is no command to run a lifecycle based on lifecycle name. So you can't do a mvn Default and expect it to run upto Default:deploy. You will have to mention a task of a cycle like test, package, clean and the life-cycle that owns this task will get active.

It does not make sense to have life-cycle as an argument. It will be confusing. For example running mvn clean is the Clean life-cycle or clean task?

Or, it will be more verbose to type mvn clean will run Clean life cycle; and mvn clean:clean will run Clean life cycle until clean task.

Maven has three life cycle. Executing a task (say task_N) of any of the life cycle will result in executing the whole life-cycle until that task (task_N). The three life cycles are Clean, Default, and Site.

For more details see here Introduction to Maven Life-cycles and task order

You see when you execute say, mvn test these are the things gets executed in that order

validate > initialize > generate-sources > process-sources > generate-resources > process-resources > compile > process-classes > post-process > generate-test-sources > process-test-sources > generate-test-resources > process-test-resources > test-compile > process-test-classes > test

You can't skip any of the default tasks. You may hook plugins that gets gets executed during a task.

There seems to be a misunderstanding. Further reading could clarify that

mvn clean

does not invoke the whole clean lifecycle. In fact there is a clean phase in the clean lifecycle. And the command executes this phase and not the lifecycle.
