Specifying a character encoding scheme

A character encoding scheme such as ASCII, UTF-8 or UTF-16 can be chosen to be used for the reading and writing of files.

The best practice is to define encoding for copying filtered resources via the property ${project.build.sourceEncoding} which should be defined in the pom properties section like this:

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

By using the above property maven-resources-plugin will automatically use this encoding.

Occasionally you need to change the encoding explicitly for different purposes. This can be done by defining the encoding via the configuration like this:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-resources-plugin</artifactId>
        <version>3.0.1</version>
        <configuration>
          ...
          <encoding>UTF-8</encoding>
          ...
        </configuration>
      </plugin>
    </plugins>
    ...
  </build>
  ...
</project>
