Maven error updating group repository metadata input contained no data
So there is no need to let them see the source code.
Just a legible document how to use the library is more than enough.
In this example we are going to see some of the capabilities from the maven local repository.
Maven is a build automation tool used mainly for java projects from apache.
Here are some big reasons you need to concern: 1) Let's imagine.
2) It's quite not convenient to update library to the newer version.
In case there is some problem, issue should be reported to developer involved to let them fix.
You can deploy artifacts to the local repository, launching the command, after running it, you can go to the local repository and search a folder for your group_id, navigate down inside the folder structure and you will find a folder with the artifact version, inside of it you will see the artifact itself.
