When building using Maven on my mac, on mvn install i get

[WARNING] Using platform encoding (MacRoman actually) to copy filtered resources, i.e. build is platform dependent!

Is it possible to either build for a given platform (Linux) or otherwise make build platform independent?

It happens when you have not provided following in your pom.xml

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Absence of this means you are using platform specific encoding and that's why the warning.

And if @Kal's answer doesn't work for you, perhaps you can learn from my last 30 minutes... below link adds an additional line to the above answer and solved my problem. My problem was related to the maven-resources-plugin 2.6, but the provider of the following solution had a different problem it solved... https://stackoverflow.com/a/3018152/2485075

For specific needs:

<!-- https://maven.apache.org/plugins/maven-resources-plugin/index.html -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
    <configuration>
        <encoding>UTF-8</encoding>
    </configuration>
</plugin>

If the plugin is already configured one should merely add

<encoding>UTF-8</encoding>
