Diego, I’m sad to hear that. I can see in the configuration that you are mixing compatibility mode (V10-13) related build goals into the mix (non-npm):
<goal>copy-production-files</goal>
<goal>package-for-production</goal>
You need to remove these. Then you should end up with this production profile (NOTE I changed the profile name to production):
<profile>
<!-- Production mode is activated using -Pproduction -->
<id>production</id>
<properties>
<vaadin.productionMode>true</vaadin.productionMode>
</properties>
<dependencies>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>flow-server-production-mode</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>build-frontend</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
Also it is recommended that you have the prepare-frontend goal in the NOT-production mode profile for vaadin-maven-plugin:
<build>
...
<plugins>
<plugin>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-maven-plugin</artifactId>
<version>${vaadin.version}</version>
<executions>
<execution>
<goals>
<goal>prepare-frontend</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
