Maven: Identify the correct dependency from given code

What is the best way to find the right dependency for a used class that are part of the maven-online-repository?

As far I see it is this approach:

  1. lookup the import (e.g. org.whatever.X;) from your code at the maven-repository online (search.maven.org).

  2. Pick one of the result list and include it in the dependency section of the POM.

  3. Hope the chosen version and artifact of the dependency matches your requirements (compiling, runtime). If not try another artifact or version.

Essentially, yes this is what you have to do to obtain libraries/modules for your project.

Something that's helped me out though with this specific problem: versioning. You can set the versions you need for each of your dependencies with <properties> -> <gson.version>2.8.1</gson.version> (for example). That way, you can guarantee that your build matches with the reqs of the class or type of code you're trying to implement.

I'd like to share my way of doing it. What do you mean by "finding the ... for a used class that are part of the ..."? Do you mean that the dependancy is already used in somewhere else, or that you only know the package name that you may need?

I would first check which version I need for the current project. If I'm working on a team project and someone has used the dependency in somewhere else, I would check their pom (to ensure we are using the same dependency).

Then I would look up the dependency in Maven repo and include it in my pom.

Hope this helps.
