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:

当前回答

这里所有的答案对我都不起作用。我用了锤子法:

find ~/.m2/ -name "*.lastUpdated" | xargs rm

这解决了问题:-)

其他回答

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

mvn clean install -e -U -Dmaven.test.skip=true

-e详细异常 -U强制更新 -DskipTests不执行测试用例，但编译测试用例类，在目标/测试类下生成相应的类文件。 -Dmaven.test。Skip =true，不执行测试用例或编译测试用例类。使用maven。测试。Skip不仅跳过运行单元测试，还跳过编译测试代码。

一个小建议。如果使用IntelliJ Idea编译器，建议清理缓存

这是Maven最烦人的事情之一。对我来说，会发生以下情况:如果我添加了一个依赖项，请求更多的依赖项，但是连接很慢，它会在下载和超时时停止。在计时时，所有尚未获取的依赖项都在.m2缓存中用占位符标记，Maven不会(永远不会)拾取它，除非我通过删除它从缓存中删除占位符条目(如前所述)。

所以就我所知，Maven或者更准确的说是Eclipse Maven插件在这方面有一个bug。应该有人报告此事。

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

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
