我正在使用Apache-ofbiz-13.07.03。我用ant构建项目。我用mysql更改了数据库。当我想加载种子/演示数据或ant start时，日志显示错误。

***我正在使用mysql-connector-java-5.1.40-bin.jar进行JDBC连接

我的实体engin.xm就像

<delegator name="default" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" distributed-cache-clear-enabled="false">

     <group-map group-name="org.ofbiz" datasource-name="localmysql"/>
    <group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
    <group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>  

</delegator>

还有我的localmysql部分
其中我的服务器IP是10.0.31.8
