将 SmartGWT 4.0 示例项目迁移到 Maven答案

【问题标题】：Migrate SmartGWT 4.0 sample project to Maven将 SmartGWT 4.0 示例项目迁移到 Maven
【发布时间】：2022-07-19 03:24:10
【问题描述】：

我目前正在尝试通过 Eclipse 将名为 BuiltinDS 的 smartGWT 4.0 示例项目迁移到 Maven，具有以下特点：

Smartgwt 4.0-pro 版
GWT 版本 2.8.1
JDK java 1.8
Eclipse 版本 2021-03
SmartGWT 库位于 NEXUS 中

这是我发现它应该具有依赖项的 Pom。

编译成功，但是当我运行 GWT 开发模式 (CodeServer) 类型的配置时，控制台给了我以下信息并且应用程序没有启动。

发布更新

首先，我尝试使用 mvn 命令中的archetype-smartgwt-example-builtinds 描述here 的原型创建示例环境（BuiltInDs），但它没有工作......那些原型似乎被弃用。

然后，我尝试了另一种方法，从 Eclipse 创建了一个 maven 项目，寻找 SmartGWT 原型，最后，我能够创建并运行 SmartGWT 示例项目（其中包括按钮等基本图形元素）以下特点：

SmartGWT 版本 6.1-p20200412
GWT 版本 2.8.0
JDK java 1.8.0_241
Apache Maven 3.6.3
Eclipse 版本 2021-03

这就是项目结构的样子。

为了运行项目，我使用以下两种配置：

另外，我附上了我在项目中使用的文件：

在已经配置环境的情况下，我想在these 和these 指示之后添加数据源。 Run_basicenv 和 Debug_BasicEnv 配置都执行成功，但是没有显示数据源文件（bufferTable.ds.xml）的信息。

之后，我尝试使用 Visual Builder 工具检查数据源，但收到此错误消息（请参阅Error.txt 文件中的详细信息）：

目前我只能访问该版本的 SmartGWT，因此如果您能帮我弄清楚我可能缺少哪些设置或依赖项，那将非常有帮助。

非常感谢您。

【解决方案1】：

几个月前，我在一个与您类似的项目中遇到了类似的问题，但没有 Maven 的参与。

对于我的问题，问题归咎于 Eclipse 版本。似乎 2020-06 之后的任何 Eclipse 版本都无法使用您的实际 Java 8 启动您的 Java 8 - GWT 项目。您写的是您使用的是 2021-03，我建议您尝试将 Eclipse 降级到版本 2020-06。

我在 Eclipse 2020-06 上使用 GWT 2.8.1 和 GWT 2.9.0 测试了我的项目，它们都运行良好。

希望对我有所帮助！

嗨，我在 2020-03、2020-06 和 2021-03 尝试了不同版本的 Eclipse，每次都得到相同的结果。
