How to create a Maven library (non-executable JAR)

Question

I am looking for a Git repo that I clone and get started on creating a simple library for Java/Maven. I assume I need to declare a mainClass which will be the interface to the library but I don't need to declare a main method? It's stupidly difficult to figure out how to create a library with Maven, I should be able to just clone a git repo skeleton project that has most things pre-configured?

So my question is - does anyone know of a good repo to clone that is a Maven library skeleton? Note that I not looking to create Maven plugin - just a library that uses Maven for dep management.

Answer 1

I have upload this repo for you. Its a very basic skeleton. Hope it helps you.

Basically it is a simple folder structure..

maven-library-skeleton
|
- src
     |
     - main
           |
           - java
- test
- pom.xml

pom.xml content is:

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <groupId>com.empty</groupId>
    <artifactId>maven-library-skeleton</artifactId>

    <name>${project.groupId}:${project.artifactId}</name>
    <description>Empty library</description>
