Create a GWT Maven Project - eclipse

Question

I'm trying to create a new project with Eclipse in order to create GWT application under maven 2 system.
I have create the project with the follow mvn command
mvn archetype:generate -DarchetypeRepository=repo1.maven.org -DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.3.0
I have installed the follow eclipse plugins:
* m2eclipse
* egit
* gwt plugin
Here my POM file:
<?xml version="1.0" encoding="UTF-8"?>

I can compile and deploy my application using the linux shell but I have many problems to build and run the application inside eclipse.
I haven't found any tutorial that explain how to create step by step a GWT application under maven inside eclipse.
Can someone help me?

Answer 1

One more option:
Make a gwt project by using the gwt plugin in Eclipse. Now you have an Eclipse gwt project.
Select the project in Project Explorer, right-click it, then choose Configure. Then select Convert to Maven Project. Now you get a gwt-maven project.
Now add necessary dependencies to pom.xml.

Answer 2

Here is the relevant (I think) section from my pom setup when I was running my GWT app with the gwt:run goal:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>gwt-maven-plugin</artifactId>
<version>2.3.0</version>
<configuration>
<runTarget>/ModuleName.html</runTarget>
<modules>
<module>${project.groupId}.package.ModuleName</module>
</modules>
<copyWebapp>true</copyWebapp>
</configuration>
<executions>
<execution>
<configuration>
<extraParam>true</extraParam>
</configuration>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
</plugin>
I should say, though, that I now use the GWT Eclipse Plugin to run my app within Eclipse, so it's been a while since I used this configuration. From what I remember reading, the "copyWebapp" "true" is one of the key pieces of configuration. It also helped me to specify the module name directly, because the gwt-maven-plugin sometimes had problems locating it.
