用mvn help:effective-settings可以查看当前生效的settings.xml：

mvn help:effective-settings

mvn -X命令可以查看settings.xml文件的读取顺序：

总结：   
maven-help-plugin是一个小巧的辅助工具，最简单的help:system可以打印所有可用的环境变量和Java系统属性。help:effective-pom和help:effective-settings最为有用。   
help:effective-pom用于查看当前生效的POM内容，指合并了所有父POM（包括Super POM）后的XML，所以可用于检测POM中某个配置是否生效   
effective-settings可用于查看当前生效的settings.xml文件内容，所以可用于判断某个settings配置是否生效
