Multiple modules in plugin configuration

[Sonnayya]

I use Eclipse for GWT development.
My GWT app has two modules: org.company.Common and org.company.Login.

Plugin in pom file:

	<plugin>
		<groupId>net.ltgt.gwt.maven</groupId>
		<artifactId>gwt-maven-plugin</artifactId>
		<configuration>
			<moduleName>org.company.Common</moduleName>
			<moduleName>org.company.Login</moduleName>
		</configuration>
	</plugin>

I run debug from Eclipse GWT plugin.
In Tomcat webapp dir file Common.gwt.xml in war file exactly matches one in source project, but file Login.gwt.xml is very simple:

<module>
  <inherits name="com.google.gwt.core.Core"/>
  <source path="client"/>
  <source path="shared"/>
  <super-source path="super"/>
</module>

When I change position of module in configuration tag Login.gwt.xml is same source but Common.gwt.xml is simple.

Thanks for reply. But I got the error.

As the error says, other goals (here generate-module) also rely on the moduleName (and moduleShortName).
You need to either skip that goal, or configure it.

IIRC, you'll also have "default" executions left that you didn't configure here. You may want to rename one of your executions accordingly: https://maven.apache.org/guides/mini/guide-default-execution-ids.html

Don't hesitate to ask for help in the GWT users group, or possibly in a Maven support group.
