Answer 1

Where does the documentation say grails-app/lib? I believe it should just be lib/
Are you sure you put the binary jar in there, and not some sort of source code jar?

您应该删除您在 grails- ap- ap 中所做的一切, 然后简单地取消线条的注释 :



    // runtime  mysql:mysql-connector-java:5.1.16 


在 grails-app/conf/ildConfig.groovy 中
