GitHub Actions does not see published artifact - maven

Question

I have 2 projects in GitHub, project A and project B. I have published artifacts via ./gradlew publish from project A to GitHub and I can see them in https://github.com/my-org/project-a/packages. I am referencing artifacts from project A in the project B, and I am able to successfully build project B on the local machine.
However, when deploying project B via GH Actions, the build fails complaining it can't find the artifacts from project A.
Execution failed for task ':***-api-models:compileKotlin'.
> Error while evaluating property 'filteredArgumentsMap' of task ':***-api-models:compileKotlin'
> Could not resolve all files for configuration ':***-api-models:compileClasspath'.
> Could not find my.org.project-a:project-a-api-models:1.0.0.
Searched in the following locations:
- https://repo.maven.apache.org/maven2/my/org/project-a/project-a-api-models/1.0.0/project-a-api-models-1.0.0.pom
- file:/root/.m2/repository/my/org/project-a/project-a-api-models/1.0.0/project-a-api-models-1.0.0.pom
- https://maven.pkg.github.com/my-org/***/my/org/project-a/project-a-api-models/1.0.0/project-a-api-models-1.0.0.pom
Here is how I published the artifacts of project A.
project A build.gradle
repositories {
mavenLocal()
mavenCentral()
maven {
name = "GitHubPackages"
url = uri("https://maven.pkg.github.com/my-org/project-a")
credentials {
username = project.findProperty("gpr.user") ?: System.getenv("GITHUB_USERNAME")
password = project.findProperty("gpr.key") ?: System.getenv("GITHUB_TOKEN")
}
}
}
publishing {
publications {
gpr(MavenPublication) {
from(components.java)
}
}
repositories {
mavenLocal()
maven {
name = "GitHubPackages"
url = uri("https://maven.pkg.github.com/my-org/project-a")
credentials {
username = project.findProperty("gpr.user") ?: System.getenv("GITHUB_USERNAME")
password = project.findProperty("gpr.key") ?: System.getenv("GITHUB_TOKEN")
}
}
}
}
Here is how I'm reading the artifacts of project A in project B.
project B build.gradle
repositories {
mavenCentral()
maven { url "https://plugins.gradle.org/m2/" }
google()
}
dependencies {
implementation "my.org.project-a:project-a-api-models:1.0.0"
The Question
How come that the packages are there in GitHub (I can see them), and I am able to download them to my local machine, but the GH Action from another project somehow does not see them?
