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:

如何强制maven更新?

当前回答

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

我们可以使用以下命令强制获取最新的发布和快照存储库更新:

mvn --update-snapshots clean install

我有同样的错误，运行mvn install -U，然后运行mvn install为我工作。

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。

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

我在另一个上下文中得到了错误。所以我的解决方案可能对其他遇到这个问题的人有用:

存在的问题: 我已将本地存储库复制到另一台计算机，该计算机没有连接到特殊存储库。因此maven尝试对照无效的存储库检查工件。

我的解决方案: 删除_maven。库文件。
