Maven dependency update on commandline
提问by cobie
I have a maven project that was built on the commandline for eclipse and one of the dependencies is constantly changing. How do I update this dependency on the commandline as I have heard that it is a bad idea to mix m2e plugin and commandline. Furthermore, I tried running mvn eclipse:eclipseon the command line and it messes up the project in eclipse removing the dependencies folder.
我有一个基于 Eclipse 命令行构建的 Maven 项目，其中一个依赖项在不断变化。我听说混合 m2e 插件和命令行是个坏主意，我如何更新对命令行的依赖。此外，我尝试mvn eclipse:eclipse在命令行上运行，它在 eclipse 中删除了依赖项文件夹，从而弄乱了项目。

Simple run your project online i.e mvn clean install. It fetches all the latest dependencies that you mention in your pom.xml and built the project
简单地在线运行您的项目，即mvn clean install. 它获取您在 pom.xml 中提到的所有最新依赖项并构建项目

mvn clean install -U
-Umeans force update of dependencies.
-U意味着强制更新依赖项。
Also, if you want to import the project into eclipse, I first run:
另外，如果要将项目导入 eclipse，我先运行：
mvn eclipse:eclipse
then run
然后运行
mvn eclipse:clean
Seems to work for me, but that's just my pennies worth.
似乎对我有用，但这只是我的一分钱。

If you just want to re-load/update dependencies (I assume, with constantly changing you mean either SNAPSHOTS or local dependencies you update yourself), you can use
如果您只想重新加载/更新依赖项（我假设，不断变化意味着您自己更新的快照或本地依赖项），您可以使用
mvn dependency:resolve
