如何在 Eclipse 中更新 maven 存储库？

假设您已经在使用 M2eclipse 插件，当它不将依赖项更新到您的回购中的最新版本时，您可以做什么？

例如，在命令行上，可以像下面这样添加 -U标志

mvn clean install -U

强制更新附件。Eclipse 内部有类似的东西吗？(它似乎并不总是能收到最新的更新。)

You can right-click on your project then Maven > Update Project..., then select Force Update of Snapshots/Releases checkbox then click OK.

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

UPDATE: In latest versions of Eclipse: Maven > Update Project. Make sure "Force Update of Snapshots/Releases" is checked.

In newer versions of Eclipse that use the M2E plugin it is:

Right-click on your project(s) --> Maven --> Update Project...

In the following dialog is a checkbox for forcing the update ("Force Update of Snapshots/Releases")

Sometimes the dependencies don't update even with Maven->Update Project->Force Update option checked using m2eclipse plugin.

In case it doesn't work for anyone else, this method worked for me:

  • mvn eclipse:eclipse

    This will update your .classpath file with the new dependencies while preserving your .project settings and other eclipse config files.

If you want to clear your old settings for whatever reason, you can run:

  • mvn eclipse:clean

  • mvn eclipse:eclipse

    mvn eclipse:clean will erase your old settings, then mvn eclipse:eclipse will create new .project, .classpath and other eclipse config files.

If Maven update snapshot doesn't work and if you have Spring Tooling, one interesting way is to remove

  • 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

Note: Maven update snapshot sometimes stops working if you use anything else i.e. eclipse:eclipse or Spring Tooling
