无法在Grails的3

Question

创建初始连接池我有一个Grails 3.2.7应用与IntelliJ IDEA的2017年1月1日。但问题是我无法创建连接池到MySql数据库（开发环境）。

这里是我的application.yml

Iam a newbi to grails 3有人可以帮我弄清楚这个问题吗？

这些依赖关系似乎丢失了你的build文件

runtime "org.apache.tomcat:tomcat-jdbc:8.5.0" 
runtime "org.apache.tomcat.embed:tomcat-embed-logging-log4j:8.5.0" 

尝试加入他们，看看它是否工作。
