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

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

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。

-U似乎强制更新所有快照依赖项。

如果你想在没有clean或-U的情况下更新单个依赖，你可以从本地repo中删除它，然后构建。

下面的例子用于更新slf4j-api 1.7.1-SNAPSHOT:

rm -rf ~/.m2/repository/org/slf4j/slf4j-api/1.7.1-SNAPSHOT
mvn compile

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