IDEA中出现插件错误

上次运行好的程序一下子运行不了了。

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:1.3.1:enforce (enforce-versions) on project rr4a-core: Some Enforcer rules have failed. Look above for specific messages explaining why the rule failed. -> [Help 1]

然后在网上找资料，有的说JDK的安装不正确，JRE安装不正确，还有是JDK的版本不对。自己看了下这些东西都没有出问题。



maven的路径出问题了，不知道什么时候它变成了默认的路径，然后修改下



编译通过。。。。
