Question

I’m facing problems with the UTF-8 encoding on Heroku. I need to pass the argument -encoding UTF-8 to javac while compiling.

How can I achieve it?

Seems like a stupid and simple question but couldn’t find any solution online.

Thank you.

Assuming you’re using Maven, you can pass compiler arguments using the maven-compiler-plugin like this:

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
          <compilerArgument>-encoding UTF-8</compilerArgument>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

(I didn’t actually test this snippet). Doc is here:
