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通过cmd编译。

但这也不起作用。

缺少一个缺少的POM文件。

请帮我解决一下这个。我从几天开始尝试这种方法，并尝试了所有我能做的事情。

谢谢。

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>
