Question

我想将Maven项目转换为App Engine项目以进行部署。但这给了我以下错误，如下面的屏幕快照所示：-

以下是我的项目属性的屏幕截图：-

除此之外，当我在本地主机上运行项目时，出现以下错误：-

HTTP错误503访问/时出现问题。原因：
Service Unavailable

因此，以下是我的pom.xml的代码，我想此文件中缺少某些内容：-

Answer 1

我不熟悉App Engine标准项目，但是您的屏幕截图看起来像您已配置了Dynamic Web Module 2.3。根据{{3}}的每个已报告问题，使用App Engine需要Dynamic Web Module 2.5。

对于同一来源，您可能还需要检查org.eclipse.wst.common.project.facet.core.xml文件中的“ jst.web”设置，并确保它与您选择的值一致。 / p>
