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:

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

我使用了IntelliJ IDE，我有一个类似的问题，为了解决这个问题，我在Maven选项卡中单击“为所有项目生成源代码和更新文件夹”。

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

您需要检查<maven_home>/conf目录下的settings.xml文件。

就我而言，我首先做的是:

mvn clean install -U

它仍然显示相同的错误，然后我关闭项目，再次重新打开它。最后工作。
