推荐答案

m2eclipse应该为您做到这一点(相关性将复制到您的本地存储库中)并构建有效的类路径. 我对已解决的依赖关系已经过时的尝试有任何疑问

m2eclipse should do this for you (dependencies will be copied to your local repository) and build a valid classpath. I you have any doubts that the resolved dependencies are outdated try

<select project> -> Context Menu -> Maven -> Update Dependencies

如果要保证所有依赖项(和插件)都在本地存储库中，则可以运行 Maven依赖插件:

If you want to guarantee that all dependencies (and plugins) are in your local repository you can run the go-offline goal from the Maven Dependency Plugin:

mvn dependency:go-offline

如果要将所有需要的依赖项复制到一个地方，请使用复制依赖目标

If you want to copy all needed dependencies to one place, use the copy-dependencies goal

mvn dependency:copy-dependencies

在这种情况下，Maven依赖项插件会将所有依赖项(包括传递性)复制到target/dependency文件夹中.

The Maven Dependency Plugin will copy all dependencies (including transitive) to the target/dependency folder in this case.

您还可以使用以下命令从eclipse运行所有这些命令:

You can run all these commands also from eclipse using:

<select project> -> Context Menu -> Run As -> Maven build... -> <type goals> -> Run
