Newbie installing a dependency following the docs

[adam-cyclones]

I am trying to work on my first Kotlin (or java ecosystem) project, my project exists and far its been good to get to grips with, but I am stuck when I want to use mongo to retrieve data from my rest calls.

Following this guage

https://quarkus.io/guides/mongodb-panache#creating-the-maven-project

I add the dependency to my pom:

But when I do this, I cant work out what the import should be, nor get it to install or resolve.

It has been 3 days now and I am about to give up I dont want to, please help :)

import as in what import statement to put in your kotlin source file or how?

[adam-cyclones]

Both really would be helpful, the docs does not cover the usage of importing mongo Panache, I have not imported a non OOTB dependency before.

[gsmet]

You added the MongoDB dependencies to the dependencyManagement section. That's not what you should do. Except for the quarkus BOM (the one with the platform properties) that should stay where it is, they should be moved with the other dependencies (like quarkus-resteasy).

The dependencyManagement section enforces versions. It does not declare the elements there as dependencies.

[adam-cyclones]

Ah okay, that makes sense, I'm a package.json guy from the land of JavaScript, this sounds like I have messed up. I will try to follow your advice thank you so much!

[gsmet]

Also, keep in mind that for each guide, you have the corresponding code in the quarkus-quickstarts repository. Typically here for MongoDB with Panache: https://github.com/quarkusio/quarkus-quickstarts/tree/main/mongodb-panache-quickstart .
