“选择不能在任何服务器上运行”

Question

我一直在 Eclipse 中开发一个动态 Web 项目。我收到此错误。

“选择不能在任何服务器上运行”。

之前它工作正常，但现在我收到此错误。我删除了服务器并再次添加它。

Project->Right Click-> Properties->Server 这里没有显示服务器，有两个选项，即恢复默认值和应用。我无法在此处添加服务器。

请告诉我想要的是这个问题。

Answer 1

我知道这有点晚了，但将来可能会对某人有所帮助。 转到 Project Facets 并确保您选择了正确的 java 版本（在我的情况下，weblogic 12.1.3 应该是 1.7）和动态 Web 模块的版本（在我的情况下应该是 3.0，而不是更大）。 为了确保您的应用程序能够运行，在项目方面的运行时选项卡中，它将显示在您的服务器上。 这肯定会起作用;)

Answer 2

右键单击项目（alt + enter）> 属性 > 项目事实。

确保您已选中 Dynamic web module (3.0) 复选框并选择正确的 java 版本 (1.8)。

Answer 3

简单：右键单击您的项目>构建路径>配置构建路径>项目构面>更改java版本。（当前版本，安装在您的计算机中）
