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。

这在Windows中也适用。

Locate the {user}/.m2/repository (Using Juno /Win7 here) In the Search field in upper right of window, type ".lastupdated". Windows will look through all subfolders for these files in the directory. (I did not look through cache.) Remove them by Right-click > Delete (I kept all of the lastupdated.properties). Then go back into Eclipse, Right-click on the project and select Maven > Update Project. I selected to "Force Update of Snapshots/Releases". Click Ok and the dependencies finally resolved correctly.

删除所有失败的下载:

find ~/.m2  -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;

windows:

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

然后在eclipse中右键单击您的项目，选择Maven->“更新项目…”，确保在结果对话框中选中“更新依赖项”，然后单击确定。

对我来说有效的解决方法如下:

将依赖项复制到pom。 < >的依赖 < groupId > org.apache.maven < / groupId > < artifactId > maven-archiver < / artifactId > <版本> 2.5版本> < / < / >的依赖 右击您的项目 选择Maven 选择更新项目 选择“强制更新快照/发布”

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

尝试执行

mvn -U clean

或者在eclipse中运行> Maven Clean和Maven >更新项目上下文菜单中的快照
