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?

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

重要的是，使用-U和不使用-U运行mvn的主要区别是-U将用远程SNAPSHOT jar覆盖本地SNAPSHOT jar。

如果你的proj中有其他模块生成jar，则从本地mvn安装创建本地快照jar。

要从Eclipse中修复此问题:

1)在Maven pom.xml中添加以下依赖项，并保存pom.xml文件。

<!-- https://mvnrepository.com/artifact/com.thoughtworks.xstream/xstream -->
<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.3.1</version>
</dependency>

2)进入项目>> Maven >>更新项目

选择项目并单击OK。

3)可选步骤，如果到第2步还没有解决，在第1步之后再执行下一步骤

转到项目>> Maven >>更新项目>>检查复选框中的“强制更新快照/发布”

选择项目并单击OK。

mvn clean install -U不工作。但是mvn -U clean后面跟着mvn clean install。

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

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”。
