GWT 和继承模块

Question

我知道有很多关于此问题的类似问题，但其中 none 对我有所帮助。我认为这可能是因为我对 maven 和 gwt 的相对技能水平，但我想寻求帮助。

我目前收到此错误：

它适用于我拥有的 com.server 包中列出的每个 class 文件。

下面是 pjg.gwt.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<!--
  When updating your version of GWT, you should also update this DTD 
reference,
  so that your app can take advantage of the latest GWT module 
capabilities.

<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.9.0//EN"

<module rename-to='com'>

  <entry-point class='com.client.pjg'/>
  <!-- Specify the paths for translatable code                    -->
  <source path='client'/>
  <source path='shared'/>
  <source path='server'/>
  <!-- allow Super Dev Mode -->
  <add-linker name="xsiframe"/>
</module>

这是我的 pom.xml:

我认为 pom 或 gwt.xml 文件中的声明存在问题，但我似乎无法弄清楚。我在 gwt.xml 中声明了源路径，我相信我在 pom.xml 中拥有我需要的一切。我唯一的另一个想法是可能有一些东西 mislabeled/titled？在这一点上真的不确定，估计另一双眼睛会有所帮助。

有什么明显的我遗漏的吗？

提前致谢！

Answer 1

您的代码正在使用 SmartGWT 库，因此需要在您的模块 (.gwt.xml) 文件中声明它，如下所示：

<inherits name='com.smartgwt.SmartGwt' />

您可以查看适用于您的版本的 SmartGwt 文档，以确保这仍然是正确的入口点。
