Using the library

Getting github-package-registry packages

The package in this repo is uploaded to the GitHub Package Registry which requires authentication. It can, for example, be solved like this in Gradle:

val githubUser: String by project
val githubPassword: String by project
repositories {
    maven {
        credentials {
            username = githubUser
            password = githubPassword
        }
        setUrl("https://maven.pkg.github.com/mikaojk/norwegian-social-security-number-validator")
    }
}

githubUser and githubPassword can be put into a separate file ~/.gradle/gradle.properties with the following content:

githubUser=x-access-token
githubPassword=[token]

Replace [token] with a personal access token with scope read:packages. See githubs guide creating-a-personal-access-token on how to create a personal access token.

Alternatively, the variables can be configured via environment variables:

• ORG_GRADLE_PROJECT_githubUser
• ORG_GRADLE_PROJECT_githubPassword

or the command line:

./gradlew -PgithubUser=x-access-token -PgithubPassword=[token]

import

Gradle(kotlin)
