报错5 ：多模块引用报错问题
Failed to execute goal on project xxx-service: Could not resolve dependencies for project
Failed to execute goal on project xxx-service: Could not resolve dependencies for project com.xxx:xxx-service:jar:1.0.0: Failed to collect dependencies at com.yyy:yyy-facade:jar:1.0.0: Failed to read artifact descriptor for com.yyy:yyy-facade:jar:1.0.0: Failure to find com.yyy:yyy:pom:1.0.0
原因：
子项目引用了父项目的POM，但没有在父项目POM目录下执行安装操作(父目录下执行mvn install)，这个问题就会出现。当一个子模块可能会依赖一个兄弟子模块而且去读取兄弟子模块的pom时，除非在父项目POM目录下至少执行一次安装，否则就会读取失败，即出现上述错误。
报错六：
Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7:generate failed: Cannot instantiate object of type .MysqlCommentGenerator
修复：根据此文档修改后，报错消失
