mvn clean package

POM.xml

Solution 1:[1]

Maven works by creating a local repository in your desktop or the machine you have installed maven and running this goal.

In the process of maven running the goal, it first tries to get all the dependent jar files from Central repository as you have listed in your comments M1 or M2 and then stores them under C:/Users/yourname/.m2/repository folder (assuming you are using a windows machine) or the corresponding user folder in other OS systems.

Then it uses the jars to run the build as required per the goals given.

Now in your case, you got to figure out a way to connect to the repositories (check your settings.xml located in the .m2 folder in your User directory) and check if you can connect to the internet central maven repositories. If not you can get the jar file and manually install them as advised in the error you have got. Once you do that I think you should get past this issue. Let me know if you still have the issues.

Solution 2:[2]

In my case, it was caused by me doing an offline build (i.e. mvn -o install) and me not having that jar installed in my local Maven repository yet. Doing an online build (mvn install) fixed it.
