See https://tbroyer.github.io/gwt-maven-plugin/codeserver.html for the differences between gwt:compile and gwt:codeserver. Here, because it looks like you have both server and client code in the same Maven project, I'd say this is because your gwt-user is in scope=provided so it's not available at runtime. You can workaround this by reconfiguring the gwt:codeserver's classpathScope: https://tbroyer.github.io/gwt-maven-plugin/codeserver-mojo.html#classpathScope
To troubleshoot: run Maven with debug logs (mvn -X gwt:codeserver), the plugin will emit two lines starting with "Classpath: " and "Arguments: " respectively that you can inspect; and you'll also see debug logs from GWT. Also, turn on failOnError, maybe there was something earlier that caused that error.
