Github user guoyuepeng commented on the issue: https://github.com/apache/incubator-griffin/pull/392 Hi @SparshSinghalHM Thanks for your PR, but we cannot use mysql in our primary pom.xml directly since its license not compatible with apache community. so if you want to use mysql as storage, please use this pom as your build pom https://github.com/apache/incubator-griffin/blob/master/service/hibernate_mysql_pom.xml Thanks for your understanding.
