Define Eclipse project encoding as UTF-8 from Maven

Question

I want to have the encoding of my project's file to be set to UTF-8.

Following maven FAQ answer, I set the project.build.sourceEncoding property to UTF-8. unfortunatly, it has no effect.

Then, by looking at a m2eclipse JIRA, I tried a workaround by defining compiler plugin sourceEncoding, but it neither worked, as I try to do that in a separate module parent pom.

Then, what is the solution to ensure my files are all in UTF-8 from maven ?

Thanks.

(A bit late) Solution / workaround I'm using to avoid inheriting MacRoman.

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-eclipse-plugin</artifactId>
        <version>2.9</version>
        <configuration>
          <additionalConfig>
            <file>
              <name>.settings/org.eclipse.core.resources.prefs</name>
              <content>
                <![CDATA[eclipse.preferences.version=1${line.separator}encoding/<project>=${project.build.sourceEncoding}${line.separator}]]>
              </content>
            </file>
          </additionalConfig>
        </configuration>
      </plugin>
    </plugins>
  </build>

Execute the command below :

mvn eclipse:eclipse
