Help / Configuring Maven pom.xml file

Security

By default our service uses very simple security model - we create unique read/write URL for each user. But this approach has its limitations - anyone who knows your URL can access your data. Because of that putting those URLs in to your pom.xml file directly will be insecure. To solve this problem you can store repository URL in ~/.m2/settings.xml

<settings>
    <profiles>
        <profile>
            <id>myMavenRepo</id>
            <activation>
                <property>
                    <name>!doNotUseMyMavenRepo</name>
                </property>
            </activation>
            <properties>
                <myMavenRepo.read.url>{{readUrl}}</myMavenRepo.read.url>
                <myMavenRepo.write.url>{{writeUrl}}</myMavenRepo.write.url>
            </properties>
        </profile>
    </profiles>
</settings>

You can't configure global Maven property. Maven properties should be located in profile element. We use fake property to make this profile always active as described here

Reading

To get data from your repository you can use read or write URLs. Configure myMavenRepo.read.url variable as described in Security section. After that you can configure your repository in /path/to/project/pom.xml file:

<project>
    ...
    <repositories>
        <repository>
            <id>myMavenRepo.read</id>
            <url>${myMavenRepo.read.url}</url>
        </repository>
    </repositories>
    ...
</project>

Publishing artifacts

To publish data to repository you can use only write URL. Configure myMavenRepo.write.url variable as described in Security section. After that modify /path/to/project/pom.xml to configure deploy plugin:

<project>
    ...
    <distributionManagement>
        <repository>
            <id>myMavenRepo.write</id>
            <url>${myMavenRepo.write.url}</url>
        </repository>
        <snapshotRepository>
            <id>myMavenRepo.write</id>
            <url>${myMavenRepo.write.url}</url>
        </snapshotRepository>
    </distributionManagement>
    ...
</project>

To upload artifacts use mvn deploy command.
