Failed to publish publication 'gpr' to repository 'GitHubPackages' because of HTTP 422 error

I am trying to publish my Katalon Studio SDK to GitHub packages.

I have been following these instructions to do so.

I created environment variables GITHUB_ACTOR and GITHUB_TOKEN on my machine, set up my build.gradle and then tried to run it.

My build.gradle looks like:

The build.gradle file

plugins {
  id 'java'
  id 'maven-publish'
  id "com.katalon.gradle-plugin" version "0.1.1"
}

group = 'com.mikewarren.katalonstudiosdk'
version = '1.0'

dependencies {
  implementation 'com.github.javafaker:javafaker:1.0.2'
}

repositories {
    mavenCentral()
}

sourceSets {
    main {
        groovy {
            srcDirs = ['Keywords', 'Libs']
            excludes = ['CustomKeywords.groovy', "Temp*.groovy"]
        }
    }
    test {
        groovy {
            srcDirs = ['Include/scripts/groovy']
        }
    }
}

publishing {
    repositories { 
        maven {
            name = "GitHubPackages"
            url = uri("https://maven.pkg.github.com/MikeWarren2014/KatalonStudioSDK")
            credentials {
                username = project.findProperty("gpr.user") ?: System.getenv("GITHUB_ACTOR")
                password = project.findProperty("gpr.key") ?: System.getenv("GITHUB_TOKEN")
            }
        }
    }
    publications {
        gpr(MavenPublication) {
            from components.java
        }
    }
}

How I tried to run it

At the BASH shell, I said:

gradle clean build --info

What happened

What ended up happening…is this:

I did a sanity check on the environment variables prior to running this script, they were initialized.

What did you try?

I tried to check the artifact ID, whatever it is in this context (is it the group and version?) and can’t seem to find it here… idk what to do here…

I tried to check if something with ${group}:${version} existed already, via this guy’s code snippet, which returned an HTTP 401 error instead. The GITHUB_TOKEN environment variable came straight from a package-read-write-authorized personal access token (classic) created on GitHub .

What is the way to fix this once and for all?!

UPDATE: I found the solution here, and it is two-fold:

  • to take care of the HTTP 422 error: It turns out that it was taking the folder name KatalonStudioSDK as the artifact ID. I fixed that by writing
artifactId = 'katalon-studio-sdk'

inside the gpr closure , and then

  • to take care of the HTTP 401 error: restart the BASH shell, so that the environment variables GITHUB_ACTOR and GITHUB_TOKEN get recognized by it
