Nexus

Running Osgiliath project behind a Nexus

To compile your project using Nexus provided third party dependencies you first have to configure your Nexus as a mirror adding these lines to your $MAVEN_HOME/conf/settings.xml

<mirror>
<mirror>
    <id>my_mirror</id>
    <mirrorOf>*</mirrorOf>
    <name>My repo</name>
    <url>repo_url/content/groups/public</url>
</mirror>
</mirror>
And finally, add an active profile mocking the Maven Central repo by the Internal Nexus url trigger:

<profiles>
<profile>
    <id>nexus</id>
    <!--Enable snapshots for the built in central repo to direct -->
    <!--all requests to nexus via the mirror -->
    <repositories>
        <repository>
            <id>central</id>
            <url>http://central</url>
            <releases><enabled>true</enabled></releases>
            <snapshots><enabled>true</enabled></snapshots>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>central</id>
            <url>http://central</url>
            <releases><enabled>true</enabled></releases>
            <snapshots><enabled>true</enabled></snapshots>
        </pluginRepository>
    </pluginRepositories>
</profile>
</profiles>
<activeProfiles>
    <activeProfile>nexus</activeProfile>
</activeProfiles>
Also, to use the Nexus instance for your intergation-tests, run your maven goals with -Dmaven.repos.urls=http://central And if it will always be the case, just add it as a property in your root pom.xml:

    <properties>...
        <maven.repos.urls>http://central</maven.repos.urls>
    </properties>
Publishing snapshots/releases to an Internal Nexus instance
To be able to publish your artifacts in your Nexus instance, edit your settings.xml file and add two ‘servers’ called ‘releases’ and ‘snapshots’ with your nexus credential

<servers>...
<server>
    <id>snapshots</id>
    <username>my_pseudo</username>
    <password>my_pwd</password>
</server>
</servers>
Then, configure the different ‘configurationManagement’ section of your parent pom.xml (here are the defaults)

<distributionManagement>
    <snapshotRepository>

        <name>Osgiliath Snapshots public</name>
        <url>https://dist.osgiliath.net/nexus/content/repositories/snapshots</url>
    </snapshotRepository>
    <repository>
        <id>releases</id>
        <name>Sonatype OSS Nexus Release Repository</name>
        <url>https://oss.sonatype.org/</url>
    </repository>
</distributionManagement>
You finally just have to mvn deploy or mvn release:perform your project to have your binaries hosted!

Nexus Pro

To use Nexus pro staging capabilities just use the default maven goal release:perform with the -Pnexus-pro profile in the command line
