4. Package – Now unit testing is done on compiled source code so it has to be merged into package in its format. For eg- JAR file packages.

5. Verify – In this phase of Maven Lifecycle, checks are executed and verified on the results of integration testing which ensures quality is met.

6. Install – In this Install phase, we will install the packages in our local system’s repository which can be used as dependencies for other local projects.
