What does Maven dependency plugin do?
The dependency plugin provides the capability to manipulate artifacts. It can copy and/or unpack artifacts from local or remote repositories to a specified location.
What is a group ID in Maven?
Every Maven artifact is grouped into a groupId, which is in itself very similar to Java package names and their organization on disk. In my example, I would like to use the groupId com.oracle for my JDBC driver. To reflect the groupId structure on disk accordingly, where com is the top level groupId and oracle the second level groupId (you can have as many levels as you like), it will have to be nested in subfolders on disk and look like: com/oracle.
What is modelVersion in Maven?
The modelVersion specifies the version of the XML model used within the file. It is information used internally by Maven — you can and should just leave it at 4.0.0. The groupId, artifactId and version contain the very same information that we have already specified with the directory structure layout: com.oracle, ojdbc, and 12.2.0.1. The name and description are optional, but while we are at it, why not just add a bit more information for future reference? Once you have saved that file as ojdbc-12.2.0.1.pom, you are good to go and can now use the Oracle JDBC driver as a dependency in your Maven projects.
What is the last in the directory structure?
Last in the directory structure is the version of the driver. Although there was the number 8 in the driver name, it does not reflect the actual version of the driver, just the JDK version for compilation as mentioned above.

Can Maven detect a mismatch of the checksum?

Introduction
You may need to add a custom JAR as a dependency to your Maven project. This tutorial shows 3 ways to do it:
1- Install manually the JAR into your local Maven repository
The first solution is to add manually the JAR into your local Maven repository by using the Maven goal install:install-file. The use of the plugin is very simple as below:
2- Adding directly the dependency as system scope
Another solution – dirty solution – is by adding the dependency as system scope and refer to it by its full path. Consider that the JAR is located in <PROJECT_ROOT_FOLDER>/lib. Then add the dependency in your pom.xml file as following:
3- Creating a different local Maven repository
The third solution is quite similar to the first one, the difference lies in the fact that the JARs will be installed in a different local Maven repository.
4- Using Nexus repository manager
The best solution is to use a Nexus Repository Manager which will contain all your JARs and you will use it as repository to download the dependency.

Repository Structure
Copying The Jar File
- Now that I have my directory structure, it is time to copy the actual file into the target folder. Maven expects the artifact itself to be named <artifact>-<version>.jar, so my ojdbc8.jar has to become ojdbc-12.2.0.1.jar. That one is easy, I can just copy and rename the file to that:
Generating The Pom File
- Now that my JAR file is in place, there is one more file to generate, which is the .pom file, short for “Project Object Model”. It resembles the fundamental unit of work in Maven and without it, Maven won’t pick up the JAR file itself. The .pom file is an XML file with the same name as the .jarfile and contains information about the artifact and it...
Optional: Generating .Sha1 Files
- For completion's sake, there is one more task left: The generation of the .sha1 files that we have seen in the repository structure above. Those .sha1 files contain checksums of their parent files and are used to verify the integrity of the parent files. In case a file would, for whatever reason, get corrupt, Maven will detect a mismatch of the checksum and complain or download the file agai…
