This Maven command installs a specific JAR file (`was_public.jar`) and...

This Maven command installs a specific JAR file (was_public.jar) and its corresponding POM file into your local Maven repository. Let's break it down step by step:

1. mvn install:install-file

This is the Maven command to manually install an external artifact (JAR file) into the local Maven repository. The local repository is where Maven stores artifacts (libraries and dependencies) for use in your projects.

2. -Dfile=<some location>/was_public.jar

This specifies the JAR file (was_public.jar) that you want to install. Replace <some location> with the actual path to the file.

3. -DpomFile=was-dependency/was_public-9.0.0.pom

This provides the path to the POM file (was_public-9.0.0.pom) for the was_public.jar. The POM file contains metadata about the library, such as its group ID, artifact ID, version, dependencies, etc. Maven uses this information to properly register the artifact.

What happens when you run this?

• Maven will place the was_public.jar and its metadata (from the POM file) into your local Maven repository (likely at ~/.m2/repository).
• This allows was_public.jar to be available as a dependency in your projects using Maven, without needing it to come from a remote repository.

Typical use case

This command is often used when:

1. You have a library (was_public.jar) that is not available in any remote Maven repository (like Maven Central or other private repositories).
2. You need to use this library in your Maven-based project and make it accessible via the local Maven repository.
