mvn jetty:run: Address already in use about gwt-maven-archetypes HOT 4 CLOSED

Either you already ran that command, or you have something else listening on the same port (defaults to 8080).

Have a look at the jetty-maven-plugin documentation for how you can change that default port: https://www.eclipse.org/jetty/documentation/9.4.x/jetty-maven-plugin.html

from gwt-maven-archetypes.

How can i specify another port . ?? what is the name of the property .?
-Djetty.http.port=8443 this line make the project run with the command line but i want to add it in the configuration file

from gwt-maven-archetypes.

From the jetty-maven-plugin documentation, apparently something like:

<plugin>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <configuration>
    <httpConnector>
      <port>8443</port>
    </httpConnector>
  </configuration>
</plugin>

Thank you very much @tbroyer 👍
