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

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

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。

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

以前版本的maven在mvn clean install中使用-U时不强制检查丢失的版本，只检查快照，但新版本支持这一点。

对于那些还在为以前的版本而挣扎的人来说，下面的内容可能会有所帮助

在Windows上:

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

在Linux上:

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

每当maven由于任何原因(连通性/不存在等)无法下载依赖项时，它将添加“。错误=不能转移工件"在依赖项名称。lastUpdate文件在$home/下的相应文件夹。m2目录。删除这些文件将迫使maven再次尝试获取依赖项。

我有同样的错误与android-maps-utils依赖。使用aar类型包在依赖部分解决我的问题。默认类型是jar，因此可能会检查在存储库中下载的依赖项类型。
