Hi

Im trying to build a GWT application using Maven, after searching the internet I haven´t found a solution.

Here the stack is :

Also I have tried mvn -e but it fails again. Any idea, please?

The plugin is attempting to add the sample project as a module to your "my-app" project. It's failing because you can only add modules to pom projects. You should either generate the archetype in an empty directory, or the directory should house a parent pom.

Well I understand that I should create a sample in the root like:

I have tried to change the command like:

mvn archetype:generate -DarchetypeRepository=https://nexus.codehaus.org/content/repositories/orgcodehausmojo-047 -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.6.1-rc

And also with :

mvn archetype:generate -DarchetypeGroupId=nexus.codehaus.org -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.6.1-rc

But then I get a FAILURE again with the same error than before
Any idea, please?

Ok I found the solution:

create the project in the root directory :

mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.5.0

Cheers!!
