问题：Maven 出现以下错误：
Missing artifact yeepay:com.cfca.pkibase:jar:1.0 pom.xml /creditcard-admin line 453 Maven Dependency Problem Description Resource Path Location Type ...project facets version
project 编译问题
1、properties->project Facets->修改右侧的version 保持一致
2、window->preferences->java->Compiler->设置右侧的Compiler compliance level
3、window->preferences->java->Installed JREs->设置或者选择右侧的Installed JREs
以上三处的jdk版本要保持一致，才能编译通过
