How to update maven repository in Eclipse?
提问by Stephane Grenier
Assuming you're already using the m2eclipse plugin, what can you do when it doesn't update the dependencies to the latest in your repo?
假设您已经在使用m2eclipse 插件，当它没有将依赖项更新到您的存储库中的最新版本时，您可以做什么？
For example, on the command line, you can just add the -Uflag as in
例如，在命令行上，您可以添加如下-U标志
mvn clean install -U
…to force the dependencies to be updated. Is there something like this within Eclipse? (It doesn't always seem to pick up the latest updates.)
...强制更新依赖项。Eclipse 中有这样的东西吗？（它似乎并不总是获取最新的更新。）

Right-click on your project and choose Maven > Update Snapshots. In addition to that you can set "update Maven projects on startup" in Window > Preferences > Maven
右键单击您的项目并选择Maven > Update Snapshots。除此之外，您可以设置“启动时更新 Maven 项目”Window > Preferences > Maven
UPDATE: In latest versions of Eclipse:
Maven > Update Project. Make sure "Force Update of Snapshots/Releases" is checked.
UPDATE：在Eclipse的最新版本：
Maven > Update Project。确保选中“强制更新快照/版本”。

In newer versions of Eclipse that use the M2E plugin it is:
在使用 M2E 插件的较新版本的 Eclipse 中，它是：
Right-click on your project(s) --> Maven --> Update Project...
右键单击您的项目 --> Maven --> 更新项目...
In the following dialog is a checkbox for forcing the update ("Force Update of Snapshots/Releases")
在下面的对话框中是一个用于强制更新的复选框（“强制更新快照/发布”）

Sometimes the dependencies don't update even with Maven->Update Project->Force Update option checked using m2eclipse plugin.
有时即使使用 m2eclipse 插件检查 Maven->Update Project->Force Update 选项，依赖项也不会更新。
In case it doesn't work for anyone else, this method worked for me:
如果它对其他人不起作用，则此方法对我有用：
mvn eclipse:eclipseThis will update your .classpathfile with the new dependencies while preserving your .projectsettings and other eclipse config files.
mvn eclipse:eclipse这将使用新的依赖项更新您的.classpath文件，同时保留您的.project设置和其他 eclipse 配置文件。
If you want to clear your old settings for whatever reason, you can run:
如果您想清除旧设置，无论出于何种原因，您都可以运行：
mvn eclipse:cleanmvn eclipse:eclipsemvn eclipse:cleanwill erase your old settings, then mvn eclipse:eclipsewill create new .project, .classpathand other eclipse config files.
mvn eclipse:cleanmvn eclipse:eclipsemvn eclipse:clean将清除您的旧设置，然后mvn eclipse:eclipse将创建新的.project、.classpath和其他 eclipse 配置文件。

If Maven update snapshot doesn't work and if you have Spring Tooling, one interesting way is to remove
如果 Maven 更新快照不起作用并且您有 Spring Tooling，一种有趣的方法是删除
- Right-click on your project then Maven > Disable Maven Nature
- Right-click on your project then Spring Tools > Update Maven Dependencies
- After "BUILD SUCCESS", Right-click on your project then Configure > Convert Maven Project
- 右键单击您的项目，然后选择 Maven > Disable Maven Nature
- 右键单击您的项目，然后选择 Spring Tools > Update Maven Dependencies
- 在“BUILD SUCCESS”之后，右键单击您的项目，然后配置 > 转换 Maven 项目
Note: Maven update snapshot sometimes stops working if you use anything else i.e. eclipse:eclipse or Spring Tooling
注意：如果您使用其他任何东西，例如 eclipse:eclipse 或 Spring Tooling，Maven 更新快照有时会停止工作
