如何强制maven更新?

我将我已经工作的项目导入到另一台计算机上，它开始下载依赖项。

显然我的网络连接崩溃了，现在我得到了以下信息:

    >Build errors for comics; org.apache.maven.lifecycle.LifecycleExecutionException:
    Failed to execute goal on project comicsTest: Could not resolve dependencies for project comicsTest:comicsTest:war:0.0.1-SNAPSHOT:
    The following artifacts could not be resolved:

What maven does is, it downloads all your project's dependencies into your local repo (.m2 folder). Because of the internet causing issues with your local repo, you project is facing problems. I am not sure if this will surely help you or not but you can try deleting all the files within the repository folder inside the .m2 folder. Since there would be nothing in the local repo, maven would be forced to download the dependencies again, thus forcing an update. Generally, the .m2 folder is located at c:users:[username]:.m2

mvn clean install -U不工作。但是mvn -U clean后面跟着mvn clean install。

以防有人只想更新项目的快照依赖项而不想安装工件:

mvn dependency:resolve -U

不要忘记在IDE中重新导入依赖项。在IDEA中，您需要右键单击pom文件，并选择Maven ->重新导入

mvn clean install -U

-U表示强制更新快照依赖项。

如果之前从未成功下载过发布依赖项，则将以这种方式更新。裁判:https://stackoverflow.com/a/29020990/32453

使用mvn clean install -U run as maven test之后，使用maven-update project更新你的项目这对我来说是可行的

您可以从Eclipse IDE中有效地完成这些工作。当然，如果你在用的话。

Project_Name->Maven->Update Project Configuration->Force Update of Snapshots/Releases
