使用com.googlecode.maven下载多个工件-下载-插件
我想使用下载-maven-plugin从Maven存储库下载几个工件
我可以下载一个很好的工件，但是当我添加一个秒时，它就被忽略了：

或者，如果有另一种方法从Maven存储库下载到文件(特别是需要从settings.xml进行身份验证的私有存储库)--例如使用货车--那么这个方法也可以工作。

https://maven.apache.org/plugins/maven-dependency-plugin/copy-dependencies-mojo.html似乎是解决所述问题的更好方法。它将：
将项目依赖项从存储库复制到定义位置的目标。
您可以运行mvn org.apache.maven.plugins:maven-dependency-plugin:copy-dependencies。这将读取POM中的依赖项，正常使用settings.xml并复制它们。默认情况下，我认为target是一个目录，但它是可配置的。
