Question

好的，我是Maven和Eclipse的新手，我必须运行一个现有的项目。我尝试使用命令eclipse:eclipse -Dwtpversion=2.0，但它显示以下错误：

[INFO]添加对WTP 2.0版的支持   [INFO]使用Eclipse Workspace：null

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

任何帮助都很有用

Answer 1

正如@JFMeier在评论中所说，命令 eclipse：eclipse 现在已被弃用。

要更新项目，请右键单击该项目，选择 Maven -> 更新项目... ->选中 强制更新快照/发布 框，然后单击确定。

那样就可以。

无法执行目标Maven / Eclipse
