What phases of the project lifecycle are necessary to prepare and execute the mvn package command, completing the artifact build?

To successfully execute the mvn package command and build the artifact, the following project lifecycle phases in Maven must be completed:

1. Validate — check the correctness of the project and its structure.
2. Compile — compile the project's source code.
3. Test — run unit tests to verify code correctness.
4. Package — package the compiled code into an artifact, such as a JAR or WAR.

The mvn package command automatically executes all phases up to and including package.

Example:

mvn package

As a result, the built artifact (e.g., myapp.jar) will appear in the target folder.
