How do I pull in a private username and password via Maven for testing?

In order to connect to an external system, for which each developer has a personal username and password, I need to pull in a username and password to my JUnit test cases:

String username = System.getProperty("ext.username");

The above line would be called inside any class inside my test folder

How can I best do this via Maven? I think the best scope for the property is inside settings.xml, but I'm not sure about the best way to transfer it from there into my code.

The problem is best solved using a Maven build profile.

In your POM you declare a default value for the properties (To prevent run-time possible errors).

<project>
..
    <properties>
        <ext.username>XXXXX</ext.username>
        <ext.password>YYYYY</ext.password>
    </properties>

Each developer can then override these properies in theor local build using a default profile specified in their settings file: $HOME/.m2/settings.xml

<settings>
    ..
    <profiles>
        <profile>
            <id>dev</dev>
            <activeByDefault>true</activeByDefault>
            <properties>
                <ext.username>XXXXX</ext.username>
                <ext.password>YYYYY</ext.password>
            </properties>
        </profile>
        ..
    </profiles>
    ..
</settings>

For those worried about security is also possible to encrypt the password.

Finally, it's possible to have multiple profiles configured. These can be chosen at run-time (using profile id) in order to support multiple build environments:

mvn -Pdev  ..
mvn -Pprod ..
