Passing VM parameter in pom.xml

My program only works with ip4 and gives an error with ip6 so I need to run the jar with

-Djava.net.preferIPv4Stack=true

Is there a way to write this line into pom.xml and whenever someone opens the jar that the application will try to connect IPv4?

No, there is no way to do that at build time. The parameter is passed to the JVM when java -jar artifact.jar is run.

Your alternative is to do that yourself in code (main method is probably the place where you can change this property the earliest possible):

public static void main(String... args) {
    System.setProperty("java.net.preferIPv4Stack", "true");
}

You can use maven-surefire-plugin :

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.21.0</version>
        <configuration>
          <systemPropertyVariables>

            <java.net.preferIPv4Stack>true</java.net.preferIPv4Stack>

          </systemPropertyVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>
