问题：Failed to execute goal on project MachineLearning: Could not resolve dependencies for project cfca.xfraud:MachineLearning:war:7.1.0.2: Failed to collect dependencies at cfca.xfraud:Base:jar:7.1.0.2: Failed to read artifact descriptor for cfca.xfraud:Base:jar:7.1.0.2: Could not find artifact cfca.xfraud:parent:pom:7.1.0.2 in nexus (http://192.168.117.7:8080/nexus/content/groups/public) -> [Help 1]

这种情况下，是因为父项目parent没有mvn clean install导致的【这里主要是项目升级版本了，以往的父项目pom版本不能用了】。

只需要在打包子项目之前，先进行父项目mvn clean install。

问题解决后

pS：解决思路:

1、先确定pom文件的正确，依赖正确

2、去仓库中看看有没有关联项目依赖的jar包以及pom文件
