Adding package dependency

Added the following elements to pom.xml:

<dependencies>
    <dependency>
        <groupId>com.mycompany.app</groupId>
        <artifactId>my-app</artifactId>
        <version>1.3-SNAPSHOT</version>
    </dependency>
</dependencies>

<repositories>
    <repository>
        <id>maven-test</id>
        <url>https://maven.pkg.github.com/jcansdale-test/*</url>
    </repository>
</repositories>

Note, we can use https://maven.pkg.github.com/jcansdale-test/* as the repository URL. The repository name is only significant when publishing packages.

Create a settings.xml file for this repository:

I'm including an XML encoded token because I don't want it be automatically deleted by GitHub when it appears on a public repository. The token is a PAT with the read:packages scope from an account that doesn't own any private packages and is therefore safe to share.

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <servers>
    <server>
      <id>maven-test</id>
      <username>jcansdale-robot</username>
      <!-- Public token with `read:packages` scope -->
      <password>&#50;&#57;&#100;&#55;&#50;&#97;&#49;&#98;&#53;&#54;&#50;&#55;&#48;&#101;&#54;&#97;&#99;&#101;&#53;&#51;&#49;&#55;&#102;&#102;&#49;&#98;&#52;&#52;&#52;&#50;&#97;&#54;&#99;&#51;&#99;&#101;&#100;&#57;&#101;&#100;</password>
    </server>
  </servers>
</settings>

If you have Docker installed, you can XML encode a read:packages scoped token like this:

docker run jcansdale/gpr encode TOKEN

Add .mvn/maven.config to use local settings file by default:

-s settings.xml

Building the project

mvn package

Clear cached packages

mvn dependency:purge-local-repository
