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

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”。

其他回答

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 -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

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。

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

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。
