Create GWT Maven Project

I am trying to create a new project with Eclipse to create a GWT application on a maven 2 system. I created a project using the following mvn command

mvn archetype:generate -DarchetypeRepository=repo1.maven.org -DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.3.0

I installed the following eclipse plugins: * m2eclipse * egit * gwt plugin

Here is my POM file:

 <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <!-- POM file generated with GWT webAppCreator --> <modelVersion>4.0.0</modelVersion> <groupId>com.mobc3.paperquid</groupId> <artifactId>Backoffice</artifactId> <packaging>war</packaging> <version>1.0.0-SNAPSHOT</version> <name>GWT Maven Archetype</name> <properties> <!-- Convenience property to set the GWT version --> <gwtVersion>2.3.0</gwtVersion> <!-- GWT needs at least java 1.5 --> <maven.compiler.source>1.5</maven.compiler.source> <maven.compiler.target>1.5</maven.compiler.target> <webappDirectory>${project.build.directory}/${project.build.finalName}</webappDirectory> </properties> <dependencies> <dependency> <groupId>com.google.gwt</groupId> <artifactId>gwt-servlet</artifactId> <version>2.3.0</version> <scope>runtime</scope> </dependency> <dependency> <groupId>com.google.gwt</groupId> <artifactId>gwt-user</artifactId> <version>2.3.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.7</version> <scope>test</scope> </dependency> </dependencies> <build> <!-- Generate compiled stuff in the folder used for developing mode --> <outputDirectory>${webappDirectory}/WEB-INF/classes</outputDirectory> <plugins> <!-- GWT Maven Plugin --> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>gwt-maven-plugin</artifactId> <version>2.3.0</version> <executions> <execution> <goals> <goal>compile</goal> <goal>test</goal> <goal>i18n</goal> <goal>generateAsync</goal> </goals> </execution> </executions> <!-- Plugin configuration.

I can compile and deploy my application using the linux shell, but I have a lot of problems creating and running the application inside eclipse.

I have not found a tutorial that explains how to create a step by step GWT application in maven inside eclipse.

Can someone help me?

Another option:

  • Create a gwt project using the gwt plugin in Eclipse. You now have a Gwt Eclipse project.
  • Select the project in Project Explorer , right-click it, then select Configure . Then select Convert to Maven Project . Now you get the gwt-maven project.
  • Now add the necessary dependencies to pom.xml .

Here is the relevant section (I think) from my pom installation when I ran my GWT application with the goal of gwt: run:

 <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 have to say, however, that now I am using the GWT Eclipse Plugin to run my application in Eclipse, so it has been a while since I used this configuration. From what I remember, "copyWebapp" "true" is one of the key components of the configuration. It also helped me specify the module name directly, because gwt-maven-plugin sometimes had problems with its localization.
