这件事也发生在我身上，对此你可能有两种解决办法

If your project consist of some external or project specificdependency in it then you have to manually add it to your M2 repo folder which is located at C:\Users\Mohit.Singh.m2\repository folder and then you have to run mvn eclipse:eclipse and then mvn clean install from the project folder if you do not have any wxternal or project sppecific dependency then you may import the project into eclipse as Existing maven project then right click on project --> GO to maven --> Click on update project a window will appear check the force snapshot download option and hit on OK

我的工作空间里只有几个项目也有类似的问题。其他具有几乎相同pom的项目根本没有错误。列出的其他答案都不能解决我的问题。我最终无意中为每个项目删除/重新应用Maven特性，错误消失了:

对于每个项目，有一个pom与“决议将不会被重新尝试…”错误:

在Eclipse中右键单击项目并选择Maven->Disable Maven Nature 右键单击Eclipse中的项目并选择Configure->Convert to Maven project

请确保。m2文件夹中的settings.XML文件是有效的 然后在cmd中使用以下命令清理存储库

cd %userprofile%\.m2\repository
for /r %i in (*.lastUpdated) do del %i

在eclipse中给出正确的maven settings .xml路径。

Windows——>首选项——> Maven——>用户设置

在“用户设置”文本框中输入正确的“setting.xml”路径

在Eclipse中: 右键单击项目->Maven->更新项目->选中“快照/版本强制更新”复选框。单击OK。
