Local Maven cache for building OpenNMS

This repository is used to setup a local Reposilite instance to cache Maven artifacts which are downloaded during a build from public Maven repositories. A local cache for Maven artifacts can have several benefits:

• Remove intermediate dependencies from public remote repositories
• Speedup downloads for artifacts in geographics other than North America or when you have low network connectivity bandwidth

👮 Requirements

• Docker with the Docker Compose plugin
• Optional: TLS reverse proxy if is exposed to the public internet
• Data is stored as a bind mount in ./data, change if you want a different path for persisting the data.

👩‍🏭 Installation and Usage

Step 1: Checkout the repository and switch working directory

git clone https://github.com/opennms-forge/maven-cache
cd maven-cache

Step 2: Set a secure initial admin password

cp env.sample .env
vi .env

Set a secure init admin password and save the file:

REPOSILITE_COMPOSE_OPTS=--token admin:<change-me>

Step 3: Start the service with

docker-compose up -d

👩‍🔧 Install a Systemd service unit

cp maven-cdn.service /etc/systemd/system
systemctl daemon-reload
systemctl enable --now maven-cdn

🕹️ Use cache with Maven

Create a settings.xml file for Maven with the following content:

<settings>
    <mirrors>
        <mirror>
            <id>{My-Maven-ID}</id>
            <name>{My-Name-For-This-Service}</name>
            <url>{My-Maven-http(s)://my-host-or-FQDN}/upstream</url>
            <mirrorOf>*</mirrorOf>
        </mirror>
    </mirrors>
</settings>

You can use it globally for Maven if you create this file in ~/.m2/settings.xml or specifically by using mvn --settings /path/to/my/settings.xml.
