Questions about adding dependencies

[hhyeok1026]

I am working on moving this project to an empty project. just for study
In the new project I made, I am not getting the dependencies of the library below.
com.github.florent37:glidepalette

However, it works fine in the original pokedex.

---

I write below in settings.gradle.kts file,
maven(url="https://oss.sonatype.org/content/repositories/snapshots/")
And I understand adding dependencies using the version catalog.

When gradle syncing, a warning is output as not resolve for the dependencies,
The class of the library could not be imported.

I commented out the function that doesn't work.
Still, I wonder why I can't import it.

Is there something I am missing?

Temporarily received com.github.florent37:glidepalette from jcenter().

And I am using androidx, but there is a warning about using android package legacy, so I checked android.enableJetifier=true in gradle.properties.

Additionally
com.android.support.test:runner:1.3.0-beta01
I couldn't get this too, but I downgraded it to version 1.0.2 and got it.
