当我创建新的maven项目时，清理并构建它我收到此错误消息。

我尝试将maven-resources-plugin-2.5.jar，maven-resources-plugin-2.5，maven-surefire-plugin-2.10.jar和maven-install-plugin-2.3.1.jar添加到 C：\ Users \ MI Synergy.m2 \ repository \ org \ apache \ maven \ plugins \ maven-resources-plugin \ 2.5 并输入命令mvn compile through cmd。

但它也不起作用。

已经有一个丢失的POM文件。

请帮我解决这个问题。我从几天开始尝试这个，并尝试了我能做的一切......

谢谢。

修改我的POM.XML

我没有遇到任何问题，我在清理安装时获得了成功

将以下内容添加到您的pom.xml

<repository>              
          <id>central</id>
          <name>Central</name>
          <url>http://repo1.maven.org/maven2</url>
</repository>

这里解决了类似的错误...
