How to use the POM

• for general information about using a parent pom take a look at http://maven.apache.org/guides/introduction/introduction-to-the-pom.html.
• it boils down to define a parent element in your own POM:

<?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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>net.oneandone.maven.poms</groupId>
        <artifactId>foss-parent</artifactId>
        <version>${project.version}</version>
    </parent>
    <groupId>sample-groupId</groupId>
    <artifactId>sample-project</artifactId>
    <version>1-SNAPSHOT</version>
    [...]
</project>

Latest releases

... may be found at Maven Central.

Rules for versions

• Major version bump for cases where the user of the pom MUST change or add stuff in her project (new file is needed, plugin or dependency not defined in the pomanymore)
• Minor version bump for cases where versions of managed dependencies or managed plugins receive a major update so most of the times a quick fix would be to freeze the versions of the aforementioned dependencies or plugins in the project's pom. This includes additions of managed plugins or dependencies as well.
• Micro version bump for cases where where versions of managed dependencies or managed plugins receive a minor update.

Releasing a project

... to Maven Central via Sonatype OSS Repository Hosting:
