将SmartGWT 4.0示例项目迁移到Maven

Question

我目前正在尝试通过smartGWT将smartGWT 4.0示例项目调用的BuiltinDS迁移到Maven，其特点如下：

2021-03

• SmartGWT
• Smartgwt 4.0版本-pro
• GWT版本2.8.1
• JDK java 1.8
• Eclipse版本库在Nexus

F 211中

这是带有我发现的依赖项的Pom。

编译是成功的，但是当我运行(CodeServer)类型的配置时，控制台提供了以下内容，并且应用程序没有启动。

Answer 1

几个月前，我在一个与你类似的项目上遇到了类似的问题，但没有Maven的参与。

对于我的问题，这个问题应该归咎于Eclipse版本。看来，2020-06之后的任何版本的Eclipse都无法用实际的Java 8启动Java 8- GWT项目。您正在使用的是2021-03，我建议您尝试将Eclipse降级到2020-06版本。

我用GWT 2.8.1和GWT 2.9.0在Eclipse2020-06上测试了我的项目，它们都运行得很好。

我希望我能帮上忙！
