I have installed the follow eclipse plugins: * m2eclipse * egit * gwt plugin
我已经安装了以下 eclipse 插件： * m2eclipse * egit * gwt 插件

I can compile and deploy my application using the linux shell but I have many problems to build and run the application inside eclipse.
我可以使用 linux shell 编译和部署我的应用程序，但是我在 eclipse 中构建和运行应用程序时遇到了很多问题。
I haven't found any tutorial that explain how to create step by step a GWT application under maven inside eclipse.
我还没有找到任何教程来解释如何在 Eclipse 中的 Maven 下逐步创建 GWT 应用程序。
Can someone help me?
有人能帮我吗？

One more option:
还有一种选择：
- 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 chooseConfigure. Then selectConvert to Maven Project. Now you get a gwt-maven project. - Now add necessary dependencies to
pom.xml.
- 使用 Eclipse 中的 gwt 插件创建一个 gwt 项目。现在您有了一个 Eclipse gwt 项目。
- 在 中选择项目
Project Explorer，右键单击它，然后选择Configure。然后选择Convert to Maven Project。现在你得到了一个 gwt-maven 项目。 - 现在将必要的依赖项添加到
pom.xml.

Here is the relevant (I think) section from my pom setup when I was running my GWT app with the gwt:run goal:
当我使用 gwt:run 目标运行 GWT 应用程序时，这是我的 pom 设置中的相关（我认为）部分：
<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.
不过，我应该说，我现在使用 GWT Eclipse 插件在 Eclipse 中运行我的应用程序，所以我已经有一段时间没有使用这种配置了。从我记得阅读的内容来看，“copyWebapp”“true”是配置的关键部分之一。它还帮助我直接指定模块名称，因为 gwt-maven-plugin 有时在定位它时遇到问题。
