<phase>jar</phase>
<goals>
<goal>jar</goal>
</goals>
</execution>
    </executions>
    </plugin>

Answer 1

you can use <encoding>UTF-8</encoding> with maven-resources-plugin 3.0.2 plugin, you can find code belop:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-resources-plugin</artifactId>
        <version>3.0.2</version>
        <configuration>
          ...
          <encoding>UTF-8</encoding>
          ...
        </configuration>
      </plugin>
    </plugins>
    ...
  </build>
  ...
</project>

and if you are using Maven 3.x then you useadd below code

<project>
  ...
  <build>

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

and Maven 2.x, use below property:

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

Answer 2

The only solution which is valid is this one:

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

This solution is not related to Maven version (apart from that Maven 2 is end of life)..

This will set this property which is picked up by all apache maven plugins (maven-compiler-plugin,maven-resources-plugin etc.) which includes maven-sources-plugin. But you should use most recent versions of the plugin and not such ancient version.
