Uploading Android native artifacts to Maven - android-studio

Question

I pushed a build artifact up to GitLab. I can see that it is there via the GitLab UI. Access to it is public, I checked by downloading using the mvn command line.
publishing {
publications {
release(MavenPublication) {
group = 'com.lowpan.m2'
artifactId = 'CHIPController'
version = '1.0.0'
artifact("third_party/connectedhomeip/libs/CHIPController.jar")
}
}
repositories {
maven {
url "https://gitlab.com/api/v4/projects/43346074/packages/maven"
name "GitLab"
credentials(HttpHeaderCredentials) {
name = 'Private-Token'
value = gitLabPrivateToken
}
authentication {
header(HttpHeaderAuthentication)
}
}
}
}
Public registry link https://gitlab.com/lowpan/maven/-/packages
So as a test I tried downloading it
repositories {
google()
mavenCentral()
maven {
name = 'GitLab'
url = 'https://gitlab.com/api/v4/projects/43346074/packages/maven'
}
}
dependencies {
// Native libs
implementation 'com.lowpan.m2:CHIPController:1.0.0'
Gradle can't find it. From the debug log gradle does not even appear to be checking my repository.

So a couple of questions...
Why can't it find the file?
I am trying to package these files, https://github.com/google-home/sample-app-for-matter-android/tree/main/app/third_party/connectedhomeip
How can I put only these files into a maven object?
How do I tell gradle to unpack them into app/third_party/connectedhomeip/...?
