Maven project dependency error in eclipse using m2e plugin (for maven)
提问by suxumuxu
I am working on a java maven project in eclipse using the m2e plugin. I updated my system and my jvm updated from icedtea-bin-6.1.11.4 to icedtea-bin-6.1.11.5. Eclipse now outputs the below error in my pom file and I can't run my project. I am new to maven and eclipse and, after a day of googling, I still haven't managed to find a solution for this.
我正在使用 m2e 插件在 eclipse 中开发一个 java maven 项目。我更新了我的系统，我的 jvm 从 icedtea-bin-6.1.11.4 更新到了 icedtea-bin-6.1.11.5。Eclipse 现在在我的 pom 文件中输出以下错误，我无法运行我的项目。我是 maven 和 eclipse 的新手，经过一天的谷歌搜索，我仍然没有找到解决方案。
I personally think that this is some sort of problem with eclipse (a misconfiguration?), because I am able to get a successful build on the command line with mvn clean install -U. Moreover, I get the same error even on a fresh eclipse install without the plugins installed.
我个人认为这是 eclipse 的某种问题（配置错误？），因为我能够在命令行上使用mvn clean install -U. 此外，即使在没有安装插件的全新 eclipse 安装中，我也会遇到同样的错误。
Error:

You have cached files in your local repository. See:Failure to transfer commons-cli:commons-cli:jar:1.0 from http://repo.maven.apache.org/maven2 was cached in the local repository
您在本地存储库中缓存了文件。看：Failure to transfer commons-cli:commons-cli:jar:1.0 from http://repo.maven.apache.org/maven2 was cached in the local repository
Try to remove either $M2_HOME/repositoryor only mentioned files from your $M2_HOME/repository:
尝试$M2_HOME/repository从您的$M2_HOME/repository以下文件中删除或仅删除提及的文件：
- commons-cli/commons-cli*
- 公地-cli/公地-cli*
