Eclipse WTP - “没有为启动配置类型 org.eclipse.jst.server.tomcat.core.launchConfigurationType 定义选项卡组” ...？

Question

当我在 Eclipse 的“服务器”选项卡上双击 Tomcat 服务器时，我将进入属性页面。该页面只有一个选项卡“概述”，并有一个红色方块作为其图标。当我单击“概述”选项卡上的“打开启动配置”链接时，我收到两条弹出消息：

创建启动配置选项卡时发生异常 原因： 没有为启动配置类型 org.eclipse.jst.server.tomcat.core.launchConfigurationType 定义选项卡组

并且：

没有为启动配置类型 Apache Tomcat 定义选项卡

Eclipse 的“错误日志”选项卡定义选项卡：

我可以做些什么来让它工作？

谢谢...

Answer 1

看来是安装问题。

尝试在干净的 Eclipse 上重新安装 WTP（您可以将其解压缩到任何您想要的位置，以免弄乱您当前的 Eclipse 安装）。

正如 WTP 下载页面中提到的，您可以尝试他们的 使用 p2 更新过程更新站点。

如果您刚刚开始使用 Eclipse 或 Eclipse Web Tools，您可能需要首先从 伽利略更新网站，因为它包含您入门所需的一切。

此 Web 工具平台更新站点假定您已安装所有先决条件。
