The addon loader module allows you to easily load addons in your program.
The module isn't on the Maven Central Repository, therefore a third-party repository is required.
You have to add the JitPack repository to you project's pom.xml file.
<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository>
</repositories>
And this dependency.
<dependency>
<groupId>com.github.aziascreations</groupId>
<artifactId>module-addonloader</artifactId>
<version>-SNAPSHOT</version>
</dependency>
If you want a specific version, you just have to change the -SNAPSHOT version to the desired commit hash or release.
If you are using another build automation tool, you can check the JitPack page to see how to do it.
You can check the wiki for a [complete guide/tour].
You can also check the tests and examples to see how to "implement" it.
