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:

如何强制maven更新?


当前回答

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。

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

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

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

如果你正在使用eclipse IDE,那么:

选择项目。 按alt+F5,更新Maven项目窗口将弹出。 检查-强制更新快照/发布,单击“确定”。

如果使用Intellij IDE

进入settings/Maven 总是更新快照
