未能执行目标 Maven/Eclipse

Question

好的，我是 Maven 和 Eclipse 的新手，我必须运行现有项目。我正在尝试使用命令 eclipse:eclipse -Dwtpversion=2.0 但它向我显示以下错误：

[INFO] Adding support for WTP version 2.0.
[INFO] Using Eclipse Workspace: null

我已经在 this question 上尝试了所有可能的解决方案，但没有奏效。我的 POM 是：

任何帮助都是有用的

Answer 1

正如@JFMeier 在评论中所说，命令 eclipse:eclipse 现已弃用。

要更新项目，右击项目，select Maven -> 更新项目... -> 勾选强制更新Snapshots/Release 并单击确定。

那就行了。
