Question

我下载了MySQL jdbc连接器的最新版本（mysql-connector-java-8.0.13），并将其放在以下文件夹中：

C：\ Users \ maria \ Desktop \ report-designer \ report-designer \ lib

它显示了以下错误：

    Driver class 'org.gjt.mm.mysql.Driver' could not be found, make sure the 'MySQL' driver (jar file) is installed.
    org.gjt.mm.mysql.Driver


    org.pentaho.di.core.exception.KettleDatabaseException: 
    Error occurred while trying to connect to the database

同时，当我以与前面所述相同的方式（上图）介绍旧版本文件（mysql-connector-java-5.1.34-bin）并删除旧版本文件时。 Pentaho向我显示了以下错误：

    Error connecting to database: (using class org.gjt.mm.mysql.Driver)
    Could not create connection to database server.

    org.pentaho.di.core.exception.KettleDatabaseException: 
    Error occurred while trying to connect to the database

最后，我尝试了While的同时，将旧版本文件（mysql-connector-java-5.1-47-bin）置于与上述相同的位置（上文），并删除了旧版本文件。 Pentaho向我显示了以下错误：

    Error connecting to database: (using class org.gjt.mm.mysql.Driver)
    Unknown database 'tower7'


    org.pentaho.di.core.exception.KettleDatabaseException: 
    Error occurred while trying to connect to the database

有人可以帮我吗？

谢谢！
