maven platform encoding

Question

when you run mvn --version part of the output includes the locale and pratform encoding. For example: Default locale: en_GB, platform encoding: Cp1252

I would like to know where it picks these up from and how they can be set

Answer 1

maven picking these values from Java system properties. Here is how you could set encoding:

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

Or:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <configuration>
      <encoding>UTF-8</encoding>
    </configuration>
  </plugin>

Or pass parameter to maven command line:

mvn -Dproject.build.sourceEncoding=UTF-8
