Requirements

Step 1 — Authenticate with GitHub Packages

GitHub Packages requires a GitHub personal access token (classic) with at least the read:packages scope, even for public packages.

Create a token at GitHub → Settings → Developer settings → Personal access tokens → Tokens (classic) and add the following server to your Maven ~/.m2/settings.xml:

<settings>
  <servers>
    <server>
      <id>github</id>
      <username>YOUR_GITHUB_USERNAME</username>
      <password>YOUR_PERSONAL_ACCESS_TOKEN</password>
    </server>
  </servers>
</settings>

Step 2 — Add the repository

Add the GitHub Packages registry to your pom.xml:

<repositories>
  <repository>
    <id>github</id>
    <url>https://maven.pkg.github.com/jeyben/fixedformat4j</url>
  </repository>
</repositories>

Step 3 — Add the dependency

<dependency>
  <groupId>com.ancientprogramming.fixedformat4j</groupId>
  <artifactId>fixedformat4j</artifactId>
  <version>1.4.0</version>
</dependency>

No GitHub account? Download manually

If you do not have a GitHub account, download fixedformat4j-1.4.0.jar directly from the 1.4.0 release page and install it into your local Maven repository:

mvn install:install-file \
  -Dfile=fixedformat4j-1.4.0.jar \
  -DgroupId=com.ancientprogramming.fixedformat4j \
  -DartifactId=fixedformat4j \
  -Dversion=1.4.0 \
  -Dpackaging=jar

After that the standard <dependency> block from Step 3 works as-is — no <repository> entry or token needed.

If you want to share the artifact across a team, deploy it to a private Nexus or Artifactory instance using mvn deploy:deploy-file with the same coordinates and your repository URL.

Logging

fixedformat4j uses SLF4J for logging. SLF4J is a logging facade — you must provide a binding on the classpath to route log output to your preferred logging framework (e.g. Logback, Log4j 2, or slf4j-simple).

Example with Logback:

<dependency>
  <groupId>ch.qos.logback</groupId>
  <artifactId>logback-classic</artifactId>
  <version>1.5.18</version>
</dependency>

If no binding is found, SLF4J will print a one-time warning and silently discard all log output — the library will still function correctly.
