What is the 'install' command in Maven and what is it used for in the build process of a project?

The install command in Maven is used to install the built artifact (such as a JAR file) into your local Maven repository on your computer. This allows other projects that use this local repository to reference this artifact as a dependency.

Typically, the build process includes the phases compile, test, package, and then install. After executing install, the artifact becomes available locally, which is convenient for development and testing before publishing it to a remote repository.

Example command:

mvn install

This will build the project, run tests, and install the result into the local repository (~/.m2/repository).
